Reverting from the change in #339105. The update was to allow tabledrag to work in fieldsets that were initially closed. Yet, this already works for the upload module. Need more detail before making change.

Updated farbtastic to core drupal 7 version. This updates fb.widgetCoords to use jQuery.offset() which changes fb.widgetCoords to be just 2 lines, is faster than the old version, and is done the jQuery way.
