Igcs 53 detect fwr configure

* Telemetry now restarts when FWR
  is removed and re-connected to 
  running app.

* Had to update to XCUnit in order to get app to
  build correctly in release mode on Xcode 6 and
  also remove un-needed files from iGCSTests
  targets build phase. (possibly was  an issue in
  Xcode 5 as well)

* missing request and heartbeat logic will be 
  tweaked in a  separate branch to improve 
  reconnect times. Currently it can take as 
  long as 12 seconds to reconnect.
