try to fix the recent network issues, the slightly more sane way. added a r_viewmodel_fov cvar, to optionally control the viewmodel's fov separately from view fov. updatesound now auto-starts the sound if it wasn't already playing, but only if a sound name was specified. small optimisation for xonotic. Delay the actual fopen until the first read. This avoids the worst of the hitches every time a footstep sound is played (no more zlib decompression). r_lightprepass now respects rtlight modes. optimised some rtlight pvs bits. should hopefully be slightly more efficient. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5186 fc73d0e0-1445-4013-8a0c-d673dee63da5
