[CA] [CA11] Moving Secondary MDF between Boats

[lwitty]

Thanks Chuck, I will give this a test next time out. If I am reading correctly, waypoints/routes/tracks will synchronize between the MDFs when Data Master is switched. So my mistake when removing the unit from the sailboat to the fishing boat was not setting it as the master before it was removed, thus losing the waypoints when re-introduced as a slave to the e125.
