/**
* @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&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.
