Subject: move attribute widgets to widgets.js file

- move @ng:repeat to widgets.js and its specs to widgetsSpecs.js
- move @ng:non-bindable to widgets.js and its specs to widgetsSpecs.js
- make widget.template suitable for attribute widgets
- fix up the js docs for attribute widgets

- * @description
- * Sometimes it is necessary to write code which looks like

- * wrapped in `ng:non-bindable` is left alone
- * @example
-    <div>Normal: {{1 + 2}}</div>
-    <div ng:non-bindable>Ignored: {{1 + 2}}</div>

-/**
- * @ngdoc directive
- * @name angular.directive.ng:repeat
- *
- * @description
- * `ng:repeat` instantiates a template once per item from a 
- * collection. The collection is enumerated with 
- * `ng:repeat-index` attribute starting from 0. Each template 
- * instance gets its own scope where the given loop variable 
- * is set to the current collection item and `$index` is set 
- * to the item index or key.
- * 
- * NOTE: `ng:repeat` looks like a directive, but is actually a 
- * attribute widget.
- * 
- * @element ANY
- * @param {repeat} repeat_expression to itterate over.
- * 
- *   * `variable in expression`, where variable is the user 
- *     defined loop variable and expression is a scope expression 
- *     giving the collection to enumerate. For example: 
- *     `track in cd.tracks`.
- *   * `(key, value) in expression`, where key and value can 
- *     be any user defined identifiers, and expression is the 
- *     scope expression giving the collection to enumerate. 
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- * Special properties set on the local scope:
- *   * {number} $index - iterator offset of the repeated element (0..length-1)
- *   * {string} $position - position of the repeated element in the iterator ('first', 'middle', 'last')
- *
- * @exampleDescription
- * This example initializes the scope to a list of names and 
- * than uses `ng:repeat` to display every person.
- * @example
-    <div ng:init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">
-      I have {{friends.length}} friends. They are:
-      <ul>
-        <li ng:repeat="friend in friends"> 
-          [{{$index + 1}}] {{friend.name}} who is {{friend.age}} years old.
-        </li>
-      </ul>
-    </div>
- * @scenario
-   it('should check ng:repeat', function(){
-     var r = using('.doc-example-live').repeater('ul li'); 
-     expect(r.count()).toBe(2);
-     expect(r.row(0)).toEqual(["1","John","25"]);
-     expect(r.row(1)).toEqual(["2","Mary","28"]);
