the game-logic. This will also make it more Source Engine compatible.
There's also a new file (hlmaterials.txt) that is subject to change which will allow you
to add many custom material definitions without hard-coding a thing. Which fixes conflicts between different GoldSrc games.
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.
