Subject: New event MEDIA_UPLOAD_FINISH

    This adds a new event MEDIA_UPLOAD_FINISH which is triggered
    when a media file is uploaded via the mediamanager.
    (The event is preventable)

    Event data:
        data[0] temporary file name (read from $_FILES)
        data[1] file name of the file being uploaded
        data[2] future directory id of the file being uploaded
        data[3] the mime type of the file being uploaded
