Many many updates: CSS changes to change appearance of tabs and buttons; shuffling of YUI css and image files; initial setup page is ready; multi-form submit is less annoying... etc...

Added rootUrl() to form action attributes; changed lookupObjectValue() calls to lookupValue() to avoid string parsing issues; added some form submission methods to XNAT.xhr.

Added <textarea> panel element; improved handling of values that are looked up from a javascript object.

Changed value/object lookup syntax to '??' - if an input value starts with '??' the following expression will be evaluated to get the value

Added /setup files; added panel.multiForm widget that will submit and reset all child <form> elements; style tweaks for panel.form and panel.multiForm widgets.

Loading and saving data for the form panels should be working across the board now. Added a page for viewing the siteConfig object - /page/admin/site-config. Moved the check to see if init and jsvars JSP tag pages have been loaded into the restricted.tag page - this allows secured content to be viewed at /app/template/Page.vm?view=admin (and anywhere else restricted content is accessed).

Updates for Spawner components: added panel.section, select.menu, select.multiple; support for 'before' and 'after' properties in YAML objects; now tab groups will not show unless they have at least one tab.

Updated admin/spawner page; fixed XNAT.table().td() - now only accepts a single argument; added panel.subhead widget for dividing panels.

Many fixes and tweaks: tabs are now grouped, added special methods for panel-specific form elements, CSS still needs tweaking.
