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.
