multi_manager entities now behave correctly when calling themselves in MULTITHREADED mode.
Remove GS_RENDERFX option. Too many entities rely on its functionality anyway.
Fixed some rendermode behaviour - ladders will no longer be visible.
You can now see the playermodel (and no longer the viewmodel) in mirrors.
Fixed a lot of warnings.
add SURF_PENETRATE, which will make bullets pass right through them when
BULLETPENETRATION is set. Go over and refactor a lot of base_client, player
and spectator code to facilitate both permanent and temporary spectators
better. Add experimental env_glow lens flare code. Fix material ID detection
bug for Q3 based BSPs. A couple helper functions were added to src/client/utils.cpp
but they are not yet final.
