changed the function that retrieves a single location to decide what to
get based on the variable type, so it doesn't need to be two seperate
functions
The Location Controller was getting too heavy so an Update and
Maintenance service class was created to offload most of it's
functionality. Location upating was moved to LocationRepository
There was also a small issue with responsive list links not adapting
properly in Safari that was fixed
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.
Seperated data logic for locations and put it into its own repository
class for better organization and readability of controller classes.
Data methods are still simple so no need for an interface class just
yet, but will probably implement at a later date
