Merge branch 'Leif' into master
fixed projectiles and added config stuff

the projectile issues was caused by a major bug in the collision system
that is now resolved
I added a configure function to the generic projectile that can be used
to configure it with a generic set of values, I think this is a bit more
flexible than just passing the config as an argument
made map more configurable
removed some print statements
removed additional print statements
yet one more print statement gone
merge master into leif
