XNAT-4426, XNAT-4400, XNAT-4345(?); reverted panels to side-by-side layout and increased the standard height of <textarea> elements; added a code editor - double-click a panel.textarea element to bring it up in a dialog for editing; select menus are properly selected; other miscellaneous stuff.

XNAT-4307: updates to DICOM SCP Receivers UI; added 'banner' notification for saving data in admin ui; removed obsolete spawner tag and view files; removed obsolete site-setup-elements.yaml (the initial setup elements are still in a separate file but will be integrated into site-admin-elements.yaml).

Refactored tabs.js to be 'universal' (instead of just for the Admin UI); fixed display (or lack thereof) of descriptions on select menus; minor style tweaks.

XNAT-4210: Site Setup page works as requested (initialized:true) is set before showing the confirmation dialog, also moved site setup functions to /scripts/xnat/app/siteSetup.js; XNAT-4192: session timer works on all pages and DOESN'T RELY ON YUI ANYMORE; more reliable lookup of Spawner™ widget methods; added hooks in form input widgets to lookup a value via AJAX using syntax: 'value: ?$ /path/to/data | prop.name';

Site setup sets initialized:true before closing the modal dialog; site setup functions moved to /scripts/xnat/app/siteSetup.js; more reliable Spawner widget method lookup - won't freak out if it can't find a method for your widget; session timer works on JSP pages and, get this... DOESN'T USE YUI ANYMORE; enhancements to xmodal dialogs - add 'keep' class to prevent destruction of modal elements when triggering a .close; probably some other stuff...

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.
