Surfaceproperty impacts are now fully done on the client. Server has no concept of
impacts beyond the point of announcing them.
The next step: NSTraceAttack should be fully shared between client/server so
that the local player doesn't need to be told about their own EV_SURFIMPACT events
by the server, thus saving a bit of bandwidth.
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.
entry.qc by pushing more code into external functions. Add support
for mods to override networked events (after we added support for
ent update overrides the other week).
