scale of landing gear ignored at launch

[pellinor0]

When launching a plane with scaled landing gear, the game uses the unscaled gear for doing the initial placement. This means that downscaled gears are up in the air, and upscaled gears are clipping the runway (exploding of breaking off if the initial shock on physics load is too high).

This seems to happen mainly to landing legs and landing gear (rover wheels seem unaffected). Those parts have rather large suspensions and small wheels, so my guess is that the problem is suspension-related.

Workaround: make the lowest part of the craft something other than an upscaled landing gear (just for launch)

(this is done by ModuleWheelBase::groundHeightOffset, which needed scaling)
