feat(ngAnimate): complete rewrite of animations

- ngAnimate directive is gone and was replaced with class based animations/transitions
- support for triggering animations on css class additions and removals
- done callback was added to all animation apis
- $animation and $animator where merged into a single $animate service with api:
  - $animate.enter(element, parent, after, done);
  - $animate.leave(element, done);
  - $animate.move(element, parent, after, done);
  - $animate.addClass(element, className, done);
  - $animate.removeClass(element, className, done);

BREAKING CHANGE: too many things changed, we'll write up a separate doc with migration instructions

+ * @name ngAnimate
+ * @description
+ *
+ * ngAnimate
+ * =========
+ *
+ * The ngAnimate module is an optional module that comes packed with AngularJS that can be included within an AngularJS
+ * application to provide support for CSS and JavaScript animation hooks.
+ *
+ * To make use of animations with AngularJS, the `angular-animate.js` JavaScript file must be included into your application
+ * and the `ngAnimate` module must be included as a dependency.
+ *
+ * <pre>
+ * angular.module('App', ['ngAnimate']);
+ * </pre>
+ *
+ * Then, to see animations in action, all that is required is to define the appropriate CSS classes
+ * or to register a JavaScript animation via the $animation service. The directives that support animation automatically are:
+ * `ngRepeat`, `ngInclude`, `ngSwitch`, `ngShow`, `ngHide` and `ngView`. Custom directives can take advantage of animation
+ * by using the `$animate` service.
+ *
+ * Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:
+ *
+ * | Directive                                                 | Supported Animations                               |
+ * |========================================================== |====================================================|
+ * | {@link ng.directive:ngRepeat#animations ngRepeat}         | enter, leave and move                              |
+ * | {@link ngRoute.directive:ngView#animations ngView}        | enter and leave                                    |
+ * | {@link ng.directive:ngInclude#animations ngInclude}       | enter and leave                                    |
+ * | {@link ng.directive:ngSwitch#animations ngSwitch}         | enter and leave                                    |
+ * | {@link ng.directive:ngIf#animations ngIf}                 | enter and leave                                    |
+ * | {@link ng.directive:ngShow#animations ngShow & ngHide}    | show and hide                                      |
+ * | {@link ng.directive:ngShow#animations ngClass}            | add and remove                                     |
+ *
+ * You can find out more information about animations upon visiting each directive page.
+ *
+ * Below is an example of how to apply animations to a directive that supports animation hooks:
+ *
+ * <pre>
+ * <style type="text/css">
+ * .slide.ng-enter > div,
+ * .slide.ng-leave > div {
+ *   -webkit-transition:0.5s linear all;
+ *   -moz-transition:0.5s linear all;
+ *   -o-transition:0.5s linear all;
+ *   transition:0.5s linear all;
+ * }
+ * 
+ * .slide > .ng-enter { }        /&#42; starting animations for enter &#42;/
+ * .slide > .ng-enter-active { } /&#42; terminal animations for enter &#42;/
+ * .slide > .ng-leave { }        /&#42; starting animations for leave &#42;/
+ * .slide > .ng-leave-active { } /&#42; terminal animations for leave &#42;/
+ * </style>
+ *
+ * <!--
+ * the animate service will automatically add .ng-enter and .ng-leave to the element
+ * to trigger the CSS animations
+ * -->
+ * <ANY class="slide" ng-include="..."></ANY>
+ * </pre>
+ *
+ * Keep in mind that if an animation is running, any child elements cannot be animated until the parent element's
+ * animation has completed.
+ *
+ * <h2>CSS-defined Animations</h2>
+ * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
+ * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
+ * and can be used to play along with this naming structure.
+ *
+ * The following code below demonstrates how to perform animations using **CSS transitions** with Angular:
+ *
+ * <pre>
+ * <style type="text/css">
+ * /&#42;
+ *  The animate class is apart of the element and the ng-enter class
+ *  is attached to the element once the enter animation event is triggered
+ * &#42;/
+ * .reveal-animation.ng-enter {
+ *  -webkit-transition: 1s linear all; /&#42; Safari/Chrome &#42;/
+ *  -moz-transition: 1s linear all; /&#42; Firefox &#42;/
+ *  -o-transition: 1s linear all; /&#42; Opera &#42;/
+ *  transition: 1s linear all; /&#42; IE10+ and Future Browsers &#42;/
+ *
+ *  /&#42; The animation preparation code &#42;/
+ *  opacity: 0;
+ * }
+ *
+ * /&#42;
+ *  Keep in mind that you want to combine both CSS
+ *  classes together to avoid any CSS-specificity
+ *  conflicts
+ * &#42;/
+ * .reveal-animation.ng-enter.ng-enter-active {
+ *  /&#42; The animation code itself &#42;/
+ *  opacity: 1;
+ * }
+ * </style>
+ *
+ * <div class="view-container">
+ *   <div ng-view class="reveal-animation"></div>
+ * </div>
+ * </pre>
+ *
+ * The following code below demonstrates how to perform animations using **CSS animations** with Angular:
+ *
+ * <pre>
+ * <style type="text/css">
+ * .reveal-animation.ng-enter {
+ *   -webkit-animation: enter_sequence 1s linear; /&#42; Safari/Chrome &#42;/
+ *   -moz-animation: enter_sequence 1s linear; /&#42; Firefox &#42;/
+ *   -o-animation: enter_sequence 1s linear; /&#42; Opera &#42;/
+ *   animation: enter_sequence 1s linear; /&#42; IE10+ and Future Browsers &#42;/
+ * }
+ * &#64-webkit-keyframes enter_sequence {
+ *   from { opacity:0; }
+ *   to { opacity:1; }
+ * }
+ * &#64-moz-keyframes enter_sequence {
+ *   from { opacity:0; }
+ *   to { opacity:1; }
+ * }
+ * &#64-o-keyframes enter_sequence {
+ *   from { opacity:0; }
+ *   to { opacity:1; }
+ * }
+ * &#64keyframes enter_sequence {
+ *   from { opacity:0; }
+ *   to { opacity:1; }
+ * }
+ * </style>
+ *
+ * <div class="view-container">
+ *   <div ng-view class="reveal-animation"></div>
+ * </div>
+ * </pre>
+ *
+ * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.
+ *
+ * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add
+ * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically
+ * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
+ * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
+ * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
+ * has no CSS transition/animation classes applied to it.
+ *
+ * <h2>JavaScript-defined Animations</h2>
+ * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
+ * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.
+ *
+ * <pre>
+ * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application.
+ * var ngModule = angular.module('YourApp', []);
+ * ngModule.animation('.my-crazy-animation', function() {
+ *   return {
+ *     enter: function(element, done) {
+ *       //run the animation
+ *       //!annotate Cancel Animation|This function (if provided) will perform the cancellation of the animation when another is triggered
+ *       return function(element, done) {
+ *         //cancel the animation
+ *       }
+ *     }
+ *     leave: function(element, done) { },
+ *     move: function(element, done) { },
+ *     show: function(element, done) { },
+ *     hide: function(element, done) { },
+ *     addClass: function(element, className, done) { },
+ *     removeClass: function(element, className, done) { },
+ *   }
+ * });
+ * </pre>
+ *
+ * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run
+ * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits
+ * the element's CSS class attribute value and then run the matching animation event function (if found).
+ * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function
+ * be executed. It should be also noted that only simple or compound class selectors are allowed.
+ *
+ * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
+ * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
+ * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
+ * or transition code that is defined via a stylesheet).
