All calls to connect for mqtt client happen on background thread.  Fixes app not responding issue.
Changed mqtt client time to wait to 30 seconds
Changed retry interval to 10 seconds
removing bind/unbind in onresume/onpause as we want service to stay during the entire life of the activity
Comments

Ping message is now parsed and creates new patient objects if needed
Responder location is now set based on broker location and reported via responder ping messages
Patients are updated when user changes info and presses save

Change patient triage to enum
Switched to triage color enum in info fragment and spinner adapter
