For some reason, although we were registering for GPS location updates
we weren't getting any. I have it set to get immediate updates and that
works for now. Added in the function of stripping out the first
direction from the Google JSON. That code could use some cleanup later,
perhaps should be in the Navigation class. Also, for sake of simplicity
I made a change that allows HTTP requests to occur in the UI thread for
at least while we are testing.
