/**
* @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> &ndash; <code>Browse</code> or <code>QuickUpload</code>.</li>
* <li><code>target</code> &ndash; the field to update in the <code><em>tabId:elementId</em></code> format.</li>
* <li><code>params</code> &ndash; additional arguments to be passed to the server connector (optional).</li>
* <li><code>onSelect</code> &ndash; a function to execute when the file is selected/uploaded (optional).</li>
* <li><code>url</code> &ndash; the URL to be called (optional).</li>
* </ul>
*
* <strong>Example 3: (Quick Upload)</strong>
*
* <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 you have a file element with an ID of <code>myFile</code>, a text
* field with an ID of <code>elementId</code> and a <code>fileButton</code>.
* If the <code>filebowser.url</code> attribute is not specified explicitly,
* the form action will be set to <code>filebrowser[<em>DialogWindowName</em>]UploadUrl</code>
* or, if not specified, to <code>filebrowserUploadUrl</code>. Additional parameters
* from the <code>params</code> object will be added to the query string. It is
* possible to create your own <code>uploadHandler</code> and cancel the built-in
* <code>updateTargetElement</code> command.<br /><br />
*
* <strong>Example 4: (Browse)</strong>
*
* <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, when the button is pressed, the file browser will be opened in a
* popup window. If you do not specify the <code>filebrowser.url</code> attribute,
* <code>filebrowser[<em>DialogName</em>]BrowseUrl</code> or
* <code>filebrowserBrowseUrl</code> will be used. After selecting a file in the file
* browser, an element with an ID of <code>elementId</code> will be updated. Just
* like in the third example, a custom <code>onSelect</code> function may be defined.
