make AddShowSearchResultsAdapter an inner class

of AddShowSearchFragment, the only place it is used. other equivelent
classes are already inner classes of where they are used.
don't use git submodule for actionbarsherlock

silly idea since we needed to have our own fork due to jar mismatches.
easier just to include the source directly.

upgrade to newest support library (revision 13) while we're at it
add menu item to refresh all shows

add to ShowsListFragment. start a RefreshShowService for each show.
only show menu item if there is 1 or more shows.
gitignore actionbarsherlock's generated files
check if views are null before hiding them after loader reset

Only seems to affect EpisodeDetailsFragment, on older api versions
(level 8 - froyo). first load completes (resets) before views have
been inflated. so when refreshViews() is called with a null cursor
check whether views are null or not before touching them
