Region identifiers queued, log view reinserted

-Created regionIdentifierQueue to hold all region identifiers for
geofences in case we enter two simultaneously before we can check them
against the new station data
-Fixes the problem of two nearby stations both triggering their
geofences at the same time and potentially nullifying the “dock here”
alert
-increased station geofence radius to 15m for testing
-put log view back in app for testing
