Merge branch '112.x-private-cars-merge' of git://github.com/BerndGabriel/simutrans-experimental.git into 112.x-private-car-merge
CHANGE: The default axle load is now the same as the weight, so as to be compatible with older versions compiled for Experimental using the previous vehicle weight system.
Fixed: convoy stuttered if it enters a brake zone already slowing down while going up-hill.
