Have land detection in GUIDED mode

[djnugent]

It would be nice if land detection worked in guided mode...all GPS modes really.

I have to switch into land mode(from guided) at 0.5 meters in order to take advantage of the land detector. It usually works but has caused me to go props first into the ground numerous times.

I think this is in ardupilot master (and Copter-3.3) already. It's just some additional lines at the top of each conrtoller (see below)
