preliminary ie support for the xforms ui.

- response.setContentType must be text/xml or responseXML will not get parsed by IE.
- getElementsByTagNameNS only works on mozilla...
- IE is much more picky about all elements explicitly setting position, top, and left, when using relative positioning
- IE's xpath implementation is non obvious and incomplete.  found a good explanation of how to use it here http://sarissa.sourceforge.net/doc/overview-summary.html#xpath.  requires a lot more manual labor to get things working, but in the end, does seem to work.  need to add in an abstraction layer...
- it fails dramatically when you terminate a list of properties with comma, meaing var bad = {foo:bar, foo2:bar2, }
var good = {foo:bar, foo2:bar2}
- ie event model is different, using the dojo abstraction layer seems to fix that, particularly for the submit buttons.  changed the way submit buttons are added to make the xforms stuff pull them rather than have the jsps add them to the xform.  thought this was necessary because of weird loading behavior in IE, but it probably wasn't.  either way - it's less code and more centralized now.
