* Making the minimum ground offset for flying a configurable offset in the OpenSim.ini. This is the code that causes you to rise off the ground when you press the fly button and attempts to keep you above ground automatically when flying in a simulator.

* minimum_ground_flight_offset, by default is 3 meters, as per Kitto Flora  See OpenSim.ini.example for an example.
