   * @fileOverview The "filebrowser" plugin, it adds support for file uploads and
   *               browsing.
   *
   * When file is selected inside of the file browser or uploaded, its url is
   * inserted automatically to a field, which is described in the 'filebrowser'
   * attribute. To specify field that should be updated, pass the tab id and
   * element id, separated with a colon.
   *
   * Example 1: (Browse)
   *
   * <pre>
   * {
   * 	type : 'button',
   * 	id : 'browse',
   * 	filebrowser : 'tabId:elementId',
   * 	label : editor.lang.common.browseServer
   * }
   * </pre>
   *
   * If you set the 'filebrowser' attribute on any element other than
   * 'fileButton', the 'Browse' action will be triggered.
   *
   * Example 2: (Quick Upload)
   *
   * <pre>
   * {
   * 	type : 'fileButton',
   * 	id : 'uploadButton',
   * 	filebrowser : 'tabId:elementId',
   * 	label : editor.lang.common.uploadSubmit,
   * 	'for' : [ 'upload', 'upload' ]
   * }
   * </pre>
   *
   * If you set the 'filebrowser' attribute on a fileButton element, the
   * 'QuickUpload' action will be executed.
   *
   * Filebrowser plugin also supports more advanced configuration (through
   * javascript object).
   *
   * The following settings are supported:
   *
   * <pre>
   *  [action] - Browse or QuickUpload
   *  [target] - field to update, tabId:elementId
   *  [params] - additional arguments to be passed to the server connector (optional)
   *  [onSelect] - function to execute when file is selected/uploaded (optional)
   *  [url] - the URL to be called (optional)
   * </pre>
   *
   * Example 3: (Quick Upload)
   *
   * <pre>
   * {
   * 	type : 'fileButton',
   * 	label : editor.lang.common.uploadSubmit,
   * 	id : 'buttonId',
   * 	filebrowser :
   * 	{
   * 		action : 'QuickUpload', //required
   * 		target : 'tab1:elementId', //required
   * 		params : //optional
   * 		{
   * 			type : 'Files',
   * 			currentFolder : '/folder/'
   * 		},
   * 		onSelect : function( fileUrl, errorMessage ) //optional
   * 		{
   * 			// Do not call the built-in selectFuntion
   * 			// return false;
   * 		}
   * 	},
   * 	'for' : [ 'tab1', 'myFile' ]
   * }
   * </pre>
   *
   * Suppose we have a file element with id 'myFile', text field with id
   * 'elementId' and a fileButton. If filebowser.url is not specified explicitly,
   * form action will be set to 'filebrowser[DialogName]UploadUrl' or, if not
   * specified, to 'filebrowserUploadUrl'. Additional parameters from 'params'
   * object will be added to the query string. It is possible to create your own
   * uploadHandler and cancel the built-in updateTargetElement command.
   *
   * Example 4: (Browse)
   *
   * <pre>
   * {
   * 	type : 'button',
   * 	id : 'buttonId',
   * 	label : editor.lang.common.browseServer,
   * 	filebrowser :
   * 	{
   * 		action : 'Browse',
   * 		url : '/ckfinder/ckfinder.html&amp;type=Images',
   * 		target : 'tab1:elementId'
   * 	}
   * }
   * </pre>
   *
   * In this example, after pressing a button, file browser will be opened in a
   * popup. If we don't specify filebrowser.url attribute,
   * 'filebrowser[DialogName]BrowseUrl' or 'filebrowserBrowseUrl' will be used.
   * After selecting a file in a file browser, an element with id 'elementId' will
   * be updated. Just like in the third example, a custom 'onSelect' function may be
   * defined.
