2) Some projectile functions have been renamed (explode
to hit etc), since not all projectiles might explode.

for irrlicht, simplifies the handling of the karts.
2) Current suspension is now used to display the wheels of karts.
This currently only works for tuxkart, all other models still
need to be modified (and these models will not display any
steering atm).
3) Refactored kart model handling: all plib specific kart model
handling is now encapsulated in karts/kart_model.?pp
4) Moved some files into new subdirs.
