simplified pagination, cleaned up front controller

Adding total actions count to location data has made it possible to
simplify backend data queries, so the custom pagination was optimized
and location repositories have been cleaned up.

the front end controller has been cleaned up as well, which has resulted
in the appropriate template being polished up as well.
