Record / launch / arm,disarm

Record me allows recording of follow me path. Saves into waypoints folder in the same format as saved points from planning mode. Added a setting to enable disable recordme.

Added arm, disarm, rtl, stabilize, and launch buttons to flight data screen. rtl and stabilize are untested.

Modified waypoints so that the first waypoint always redefines your home
location.

Added onpause, onresume, and ondestroy methods to rc mode. There was an
error where when you switched to rc mode more than once after the app
was started it would not work. These methods resolved the problem.

Changed the screen to always be in landscape mode for most of the
activities. I was noticing some force close errors intermittently when
switching orientations or screen timeout. I suspect this may have to do
with onpause and on resume and ondestroy not being included in the
flight data mode or it could be because of the layout change I made.
