/*
Queue Plug-in
Features:
*Adds a cancelQueue() method for cancelling the entire queue.
*All queued files are uploaded when startUpload() is called.
*If false is returned from uploadComplete then the queue upload is stopped.
If false is not returned (strict comparison) then the queue upload is continued.
*Adds a QueueComplete event that is fired when all the queued files have finished uploading.
Set the event handler with the queue_complete_handler setting.
