Done.

In plugin files, 'angular-bootstrap' should be required, and 'ui.bootstrap' should be used as module dependency.

Example:
```javascript
define([
    ...
    'angular-bootstrap'
    ...
], function( ... ){
    return function() {
        var module = angular.module('articles', ['articles.resources', 'ui.bootstrap']);
        ...
    };
});
```
