/**
* Select file to open or save dialog
*
* This dialog can be called from applications to open or store files from the VFS.
*
* There are the following ($_GET) parameters:
* - menuaction=filemanager.filemanager_select.select (required)
* - mode=(open|open-multiple|saveas|select-dir) (required)
* - method=app.class.method (required callback, gets called with id and selected file(s))
* - id=... (optional parameter passed to callback)
* - path=... (optional start path in VFS)
* - mime=... (optional mime-type to limit display to given type)
* - label=... (optional label for submit button, default "Open")
*
* The application calls this method in a popup with size: 640x580 px
* After the user selected one or more files (depending on the mode parameter), the "method" callback gets
* called on server (!) side. Parameters are the id plus the selected files as 1. and 2. parameter.
* The callback returns javascript to eg. update it's UI AND (!) to close the current popup ("window.close();").
