Improve collision for projectiles

Browse source 
This does a few things:

-projectiles now use clipmovex() instead of clipmove() (this is like CON_CLIPMOVENOSLIDE)
-the z distances passed to clipmove() are now calculated from the sprite's size instead of being hard-coded
-projectiles now move as if they had SFLAG_NOCLIP applied for the first tic after spawning
