casetracker 5.x-1.0

 * hook_uninstall() has been added to basic, core, and mail.
 * basic node types renamed: casetracker_basic now ships with node types named
   casetracker_basic_project (and _case) as opposed to the original form of
   casetracker_project. this renaming was a paranoid sideeffect of adding a
   hook_uninstall() which would DELETE node types named casetracker_project.
   we felt that such a name would be relatively common for custom CCK-like
   installations, and didn't want to see accidental deletions when and if
   casetracker_basic.module was ever uninstalled. a hook_update() for case
   tracker will rename all "casetracker_project" (and "case") types to include
   the "basic" string, and hope we don't trounce non-basic types.
 * bug: empty case number on the "Jump to case number" block will now
   correctly say "Case number not required". However, the fix requires
   some CSS magick which doesn't actually work in IE 6. Oh well.
