Spoike 71319a8852 add hud_miniscores_show cvar to hide the mini deathmatch overlay 
fix some issues with ezhud. ownfrags, text alphas, RGB player colours.
tweak gamecontroller input a little, to make axis slightly more usable.
fix issue with menuqc/csqc not being able to query binds reliably.
fix csqc gravitydir.
bump r_particle_tracelimit so that its no longer a limitation by default.
tweak fog to allow far-clip-plane culling on entities (but still not on world, due to issues with glClear).
fix performance issue with q1bspx BRUSHLIST lump.
fix mvd recording bug.
fix limitation that becomes apparent on maps with lots of ents visible at once. will now use more bandwidth in such cases, however.
