Subject: altosdroid: Add new "TelemetryReader" class to handle Telemetry

* Add MSG_TELEMETRY messages to both AltosDroid and TelemetryService
  to handle passing of AltosState object all the way back to the UI.
* Remove linkedblockinglist from TelemetryService
* (MSG_TELEMETRY is a rename of MSG_INCOMING_TELEM in AltosDroid)
* commented code in case statement inside AltosDroind - won't work with
  the objects it is currently passed.
* Add new "MSG_DEVCONFIG" message to AltosDroid - allows TelemetryService
  to pass information about the connected device back to the UI.
