Collision Detection Improvement

I haven’t heard any comments re: the change, so I’m going to assume no objections, in which case I am going to commit the collision stuff. The Picking will be in part II. I just wanted to get the new collisions up for some work Renanse is doing.

Ray picking should be just a copy/paste right? Did you get my ray pick code?

mostly cut and paste. Need to change some things for consistency.

committed (slight bug, will be fixed soon with Cep’s help :wink: )
