* Removed name restrictions on pak files.
* Removed restriction on number of files in a pak.

* Fixed bug in texture loader where free slots weren't being reused.
* Added games menu.
* Added r_rapidfire cvar to control "rapid fire muzzleflash" dynamic lights (default 0).
* Fixed quoth mods not getting hipnotic hud layout.
* Reworked particle system to allow for multiple textures and adjustable render params (still classic system though).
* Increased progs stack depth and size.
* Fixed occasional lockup in SV_TouchLinks (credit Tyrann for fix, Spirit for publicising the bug).
* Added "gamedir" command (same behaviour as "game").

* Added (buggy) automap - use "toggleautomap" command.
* Implemented several QIP bugfixes.

* Implemented basic DP extensions framework (don't get excited - no extensions implemented yet!)
* Added sv_oldvelocity cvar (default 1) to revert velocity bounding to original (fixed method changes gameplay).
* Made all cvars in sv_phys.cpp server cvars (broadcast if changed) - (seems the right thing to do).
* Reworked translucency handling again, added independent water/lava/slime/tele sliders and "lock alpha sliders" cvar (r_lockalpha, default 1).
* Removed gl_flashblend 1 mode (it was nice to have it for completeness sake, but when PS 2.0 is needed is this really necessary?)
* Fixed static entities not frame interpolated.
* Added cl_crossx and cl_crossy functionality.
* Added scr_crosshairscale (consistency with fitzquake) and scr_crosshaircolor (0-13, palette lookup based, default 0).
