Reduces lag due to less compilation checks;  we now only check it if the .css has not already been added to the page and it also skips a cache/file update  check if we are NOT in DEVELOPMENT and the .css file already exists (it will be the old .css file).
Change version check reporting to be more intuitive; noting if there is a full version upgrade (package) or only a patch available to the currently installed version...keeping in mind a patch can ONLY be applied to that version.
Updates the manager users views to use simple buttons instead of full links/buttons w/ text; updates manage groups views to display number of group members
Adds a new upgrade script to fix some leftover permission problems from the 2.2.0 upgrade where we trimmed the controller names but sometimes failed to update the permissions entries, therefore the permissions won't work properly.  Also cleaned up the upgrade container2 script to run correctly now.
Fixes the update permissions upgrade script
