fixed spellling in gcs msg

Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Add all handle message,
Change MAV_CMD_NAV_ROI to MAV_CMD_DO_SET_ROI
Reformate comments,

fixes issue#724

this allows for automatic engine start and restart

- also changed order of landing slope calc but is functionally the same

0 to crosstrack from center of waypoint, 1 to crosstrack from tangent exit location

this distinguishes between VTOL and fixed wing loiter targets

Deleted commands_process as it had 2 lines of useful code left, and was cleaner to move the remaining two lines into the caller case

@Description: This parameter reduces the pitch minimum limit of an auto-takeoff just a few seconds before it reaches the target altitude. This reduces overshoot by allowing the flight controller to start leveling off a few seconds before reaching the target height. When set to zero, the mission pitch min is enforced all the way to and through the target altitude, otherwise the pitch min slowly reduces to zero in the final segment. This is the pitch_min, not the demand. The flight controller should still be commanding to gain altitude to finish the takeoff but with this param it is not forcing it higher than it wants to be. (+1 squashed commits)

Plane: take advantage of L1 stale flag and correctly inhibit flight stage if not lined up on approach

the glide_slope gets calculated every time there's a major event such as mission item change or wp_proportion change so its good to update the flight stage then too because.
also logging stage when stage changes, might as well get an extra data point in there when it's timely

- except loiter_unlimited because it never exits

- except loiter_unlim which uses RTL_loiter, although I'm not sure why.
