refactor($route): pull $route and friends into angular-route.js

$route, $routeParams and ngView have been pulled from core angular.js
to angular-route.js/ngRoute module.

This is was done to in order keep the core focused on most commonly
used functionality and allow community routers to be freely used
instead of $route service.

There is no need to panic, angular-route will keep on being supported
by the angular team.

Note: I'm intentionally not fixing tutorial links. Tutorial will need
bigger changes and those should be done when we update tutorial to
1.2.

BREAKING CHANGE: applications that use $route will now need to load
angular-route.js file and define dependency on ngRoute module.

Before:

```
...
<script src="angular.js"></script>
...
var myApp = angular.module('myApp', ['someOtherModule']);
...
```

After:

```
...
<script src="angular.js"></script>
<script src="angular-route.js"></script>
...
var myApp = angular.module('myApp', ['ngRoute', 'someOtherModule']);
...
```

+/**
+ * @ngdoc directive
+ * @name ngRoute.directive:ngView
+ * @restrict ECA
+ *
+ * @description
+ * # Overview
+ * `ngView` is a directive that complements the {@link ngRoute.$route $route} service by
+ * including the rendered template of the current route into the main layout (`index.html`) file.
+ * Every time the current route changes, the included view changes with it according to the
+ * configuration of the `$route` service.
+ *
+ * Additionally, you can also provide animations via the ngAnimate attribute to animate the **enter**
+ * and **leave** effects.
+ *
+ * @animations
+ * enter - happens just after the ngView contents are changed (when the new view DOM element is inserted into the DOM)
+ * leave - happens just after the current ngView contents change and just before the former contents are removed from the DOM
+ *
+ * @scope
+ * @example
+    <example module="ngViewExample" deps="angular-route.js" animations="true">

+   *    `$location.path` will be updated to add or drop the trailing slash to exactly match the
+   *    route definition.
+   *
+   *      * `path` can contain named groups starting with a colon (`:name`). All characters up

+   *        when the route matches.
+   *      * `path` can contain named groups starting with a star (`*name`). All characters are
+   *        eagerly stored in `$routeParams` under the given `name` when the route matches.
+   *
+   *    For example, routes like `/color/:color/largecode/*largecode/edit` will match
+   *    `/color/brown/largecode/code/with/slashs/edit` and extract:

+   *      created scope or the name of a {@link angular.Module#controller registered controller}
+   *      if passed as a string.
+   *    - `controllerAs` – `{string=}` – A controller alias name. If present the controller will be
+   *      published to scope under the `controllerAs` name.
+   *    - `template` – `{string=|function()=}` – html template as a string or function that returns
+   *      an html template as a string which should be used by {@link ngRoute.directive:ngView ngView} or
+   *      {@link ng.directive:ngInclude ngInclude} directives.
+   *      This property takes precedence over `templateUrl`.

+   *    - `templateUrl` – `{string=|function()=}` – path or function that returns a path to an html

+   *
+   *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
+   *      be injected into the controller. If any of these dependencies are promises, they will be
+   *      resolved and converted to a value before the controller is instantiated and the
+   *      `$routeChangeSuccess` event is fired. The map object is:
+   *
+   *      - `key` – `{string}`: a name of a dependency to be injected into the controller.
+   *      - `factory` - `{string|function}`: If `string` then it is an alias for a service.
+   *        Otherwise if function, then it is {@link api/AUTO.$injector#invoke injected}
+   *        and the return value is treated as the dependency. If the result is a promise, it is resolved
+   *        before its value is injected into the controller.
+   *
+   *    - `redirectTo` – {(string|function())=} – value to update
+   *      {@link ng.$location $location} path with and trigger route redirection.
+   *
+   *      If `redirectTo` is a function, it will be called with the following parameters:

+   *      - `{string}` - current `$location.path()`
