xforms dojo to mootools port.

- ported xforms javascript codebase to mootools.  mostly complete - a few dangling effects and dom manipulation functions still use dojo.  these should be removed at which point it will no longer be necessary to load dojo.js which should save a second or so on load time.  a few of the date widgets and slider still use dojo widgets.  this can probably stay as dojo can be loaded only if those widgets are used.
- performance tuning of xforms js codebase.  about %40 improvement in load time for large forms with lots of widgets.
- switching wizards into almost standards compliance mode so that things will lay out properly in IE.
- lots of layout cleanup and off by pixel issues, particularly for IE.
- putting in an uncompressed version of mootools which includes some libraries needed by xforms - particularly all native objects, Element.Event, Window.DomReady, XHR and Ajax.  at some point dojo effects should likely be replaced with those in mootools.
