Android: When entering follow-me update the mode fragment
Follow-me: Disable follow-me when the pause button is pressed.
Follow-me: When follow-me is enable do not highlight the pause button
Follow-me: Create a state variable on the follow-me class
This cleans-up the code a bit. And enables us to determine the current state of follow-me from external code, like to querry it's enabled but waiting for GPS.
Follow-me: Make the follow-me button statefull
Follow-me: Stop the copter when commanded from the pebble, instead of switching to loiter.
