Added some missing file (wops!), made the hull body and radar body be
the same multi-fixture body, so i've also removed the sub-actor array
inside the actor, with can lead to a tricky problem adding sub-actor at
runtime, and also should give a little more physic efficiency.
Finally moved the fixture creation on a basic BluePrint class.

I think that part is over for now, it is time to play with compression
and network syncronization, withc should be archivied just adding a
listener (ActorListener) to the body. Please note this listener aren't
syncronized.
