add gear warning to runtime log to see the status of best alternate which is needed for mountain flying.

initialize as already warned to prevent warning just after free flight detect.
Add "Port" parameter in live Tracker config (default : 80)
corrected AutoQNH Altitude display in  feet (number was in meter but unit was feet)
LK now receives the also the QNH form the V7, so it is also bidirectional now

removed compiler warning in Westerboer driver

GearWarning fixes: nowGearWarning and noMessages reset when on ground, to allow full reset before a new flight start.
NoMessages renamed noMessages, because we keep the uppercase leading only for globals.
option MAX_NO_GEAR_WARNING moved to FreeFlight, out of option because it is not an option and it is used only here.
