fteqw/engine/server/sv_main.c
Spoike 8d09710ed1 lightprepass is functional again. still diffuse lighting only. supports shadowmaps but no other weird light info. 
added 'pkg' console command. will still need more tweaking.
r_renderscale < 0 means nearest filtering (may need a vid_restart for that to take effect though).
fteqccgui: added 'make installer' options.
fteqcc: fix framemacro issue that was breaking due to invalid dupes in hipnotic's code
cl_lerp_smooth: by default now enabled for singleplayer as well as just demos. this smooths out platforms etc.
q2 demos: explicitly recognise .dm2 extension, to try to avoid issues.

==============================================================================
PACKET FILTERING
You can add or remove addresses from the filter list with:
addip <ip>
removeip <ip>
The ip address is specified in dot format, and any unspecified digits will match any value, so you can specify an entire class C network with "addip 192.246.40".
Removeip will only remove an address specified exactly the same way. You cannot addip a subnet, then removeip a single host.
listip
Prints the current list of filters.
writeip
Dumps "addip <ip>" commands to listip.cfg so it can be execed at a later date. The filter lists are not saved and restored by default, because I beleive it would cause too much confusion.
filterban <0 or 1>
If 1 (the default), then ip addresses matching the current list will be prohibited from entering the game. This is the default setting.
If 0, then only addresses matching the list will be allowed. This lets you easily set up a private game, or a game that only allows players from your local network.
