Movement tests

Well, I *think* i've got basic movement nailed, it seems to fly nicely to me now. Feel free to 'play now' and try it Smiling.

Currently there are some diagnosic lines present, which show the fly by wire working under the hood Smiling

Velocity and thrust vector debug lines
Red/Green/Blue are local x/y/z axis, orange is current velocity vector, cyan is current thrust vector

Shields are next I think Smiling
