Form validation issues

This fixes a few problems with formvalidation.js as listed on the tracker here: http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_item_id=33195&start=0

These fixes are only in the uncompressed file. I was wondering if Joomla! has a preferred minifier. Let me know what it is and I'll make the compressed file too.
