casetracker 5.x-1.1

 * "Case States" now has a description in the admin/ blocks.
 * #108322: cbutera, jo1ene, et. al: PHP 5 compatibility fixes.
 * #107178: Breadcrumbs only show up on full $page view. Whoopsie.
 * #107548 by kbahey: allow mail clients to thread with In-Reply-To.
 * Fixed rare scenario where comment old/new would show up on non-cases.
 * #105799: casetracker/cases and projects tables have more css classes.
 * #65571: Existing nodes without CT information now receive it after editing.
 * #104048 and #104201: changed the way the "Default assigned user" setting
   works. It now only prefills the field on initial case submission. The
   "Assigned" field in the theme is now properly theme_username()'d, and
   "Assign To" is no longer a required field (so you can delete the value
   to set the case as "assigned" to the Anonymous user).
