Massive CTF updates

It also breaks one map (can't remember the name) where flags are next to each other separated by bars. But the map sucks anyway so screw it.

Perhaps the flag passing needs to obey certain clipping? Let's say there is player clip applied then the flag should not be able to penetrate it. The map really should have player clip applied to such an area anyway.

I'm aware of this map and it's problem, actually.... unfortunately, I can't actually fix this problem from code, it is a map problem (it is lacking proper clipping, the wall is too thin)-- and for reference, it was possible to drop the flag through the wall there before too, so this is nothing new.

Additionally to be clear, passing doesn't work through this wall-- the tracing knows there is a wall there and doesn't allow a pass between it.
