Collision Bitmask Jar

[Gornova]

See http://slick.javaunlimited.net/viewtopic.php?p=18182 put into MarteEngine as optional Method for collision checks?

First we need to get the stencil bit stuff cleared which is necessary for the bitmap mask stuff to work.
Then we need to decide which approach we prefer (R.D. or shiroto).
And then we need to see how performance expensive it is if we check entities one on one (as we need to do collisionstart/collisionend around the check) or how easily we can add that in some batch mode (collisionstart - then all collision checks with entities - finally collisionend).
It's more a nice to have IMHO.

Ok, for now put on hold until we clean up some code and some Issues :D
