Created a new config variable, replacing the old GOOGLE_MAPS_PLAY_SER…

…VICES_VERSION which (#14)

was used to power the version pin for both google maps and location play services dependencies.

Problem is these 2 packages does not follow the same version scheme, it doesn't make sense for
them to share the same variable. This will allow specific organizations to use a newer version
without necessary updating the plugin itself.

Additionally, both the maps and location dependencies were updated to the current latest available.
