try to do something about crazy cursor biases in games that are not likely to get the QSG cursor. fix unvised q3bsp pvs. again. add cl_delay_packets cvar as a clientside analogue to sv_minping (which is often unchangeable by the actual players). fix a qcc issue with static locals screwing everything up. fix dpmaster issues when NQPROT isn't defined. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5168 fc73d0e0-1445-4013-8a0c-d673dee63da5
