-  * @fileOverview The "filebrowser" plugin that adds support for file uploads and
-  *               browsing.
-  *
-  * When a file is uploaded or selected inside the file browser, its URL is
-  * inserted automatically into a field defined in the <code>filebrowser</code>
-  * attribute. In order to specify a field that should be updated, pass the tab ID and
-  * the element ID, separated with a colon.<br /><br />
-  *
-  * <strong>Example 1: (Browse)</strong>
-  *
-  * <pre>
-  * {
-  * 	type : 'button',
-  * 	id : 'browse',
-  * 	filebrowser : 'tabId:elementId',
-  * 	label : editor.lang.common.browseServer
-  * }
-  * </pre>
-  *
-  * If you set the <code>filebrowser</code> attribute for an element other than
-  * the <code>fileButton</code>, the <code>Browse</code> action will be triggered.<br /><br />
-  *
-  * <strong>Example 2: (Quick Upload)</strong>
-  *
-  * <pre>
-  * {
-  * 	type : 'fileButton',
-  * 	id : 'uploadButton',
-   * 	filebrowser : 'tabId:elementId',
-   * 	label : editor.lang.common.uploadSubmit,
-   * 	'for' : [ 'upload', 'upload' ]
-   * }
-   * </pre>
-   *
-   * If you set the <code>filebrowser</code> attribute for a <code>fileButton</code>
-   * element, the <code>QuickUpload</code> action will be executed.<br /><br />
-   *
-   * The filebrowser plugin also supports more advanced configuration performed through
-   * a JavaScript object.
-   *
-   * The following settings are supported:
-   *
-   * <ul>
-   * <li><code>action</code> – <code>Browse</code> or <code>QuickUpload</code>.</li>
-   * <li><code>target</code> – the field to update in the <code><em>tabId:elementId</em></code> format.</li>
-   * <li><code>params</code> – additional arguments to be passed to the server connector (optional).</li>
-   * <li><code>onSelect</code> – a function to execute when the file is selected/uploaded (optional).</li>
-   * <li><code>url</code> – the URL to be called (optional).</li>
-   * </ul>
-   *
-   * <strong>Example 3: (Quick Upload)</strong>
-   *
-   * <pre>
-   * {
-   * 	type : 'fileButton',
-   * 	label : editor.lang.common.uploadSubmit,
-   * 	id : 'buttonId',
- 64  * 	filebrowser :
- 65  * 	{
- 66  * 		action : 'QuickUpload', // required
- 67  * 		target : 'tab1:elementId', // required
- 68  * 		params : // optional
- 69  * 		{
- 70  * 			type : 'Files',
- 71  * 			currentFolder : '/folder/'
- 72  * 		},
- 73  * 		onSelect : function( fileUrl, errorMessage ) // optional
- 74  * 		{
- 75  * 			// Do not call the built-in selectFuntion.
- 76  * 			// return false;
- 77  * 		}
- 78  * 	},
- 79  * 	'for' : [ 'tab1', 'myFile' ]
- 80  * }
- 81  * </pre>
- 82  *
- 83  * Suppose you have a file element with an ID of <code>myFile</code>, a text
- 84  * field with an ID of <code>elementId</code> and a <code>fileButton</code>.
- 85  * If the <code>filebowser.url</code> attribute is not specified explicitly,
- 86  * the form action will be set to <code>filebrowser[<em>DialogWindowName</em>]UploadUrl</code>
- 87  * or, if not specified, to <code>filebrowserUploadUrl</code>. Additional parameters
- 88  * from the <code>params</code> object will be added to the query string. It is
- 89  * possible to create your own <code>uploadHandler</code> and cancel the built-in
- 90  * <code>updateTargetElement</code> command.<br /><br />
- 91  *
- 92  * <strong>Example 4: (Browse)</strong>
- 93  *
- 94  * <pre>
- 95  * {
- 96  * 	type : 'button',
- 97  * 	id : 'buttonId',
- 98  * 	label : editor.lang.common.browseServer,
- 99  * 	filebrowser :

-102  * 		url : '/ckfinder/ckfinder.html&type=Images',
-103  * 		target : 'tab1:elementId'
-104  * 	}
-105  * }
-106  * </pre>
-107  *
-108  * In this example, when the button is pressed, the file browser will be opened in a
-109  * popup window. If you do not specify the <code>filebrowser.url</code> attribute,
-110  * <code>filebrowser[<em>DialogName</em>]BrowseUrl</code> or
-111  * <code>filebrowserBrowseUrl</code> will be used. After selecting a file in the file
-112  * browser, an element with an ID of <code>elementId</code> will be updated. Just
-113  * like in the third example, a custom <code>onSelect</code> function may be defined.
