Spoike eefc950400 particles: rework r_effect, such that its possible to project particles forwards 
particles: add an emiteffectnum field (and support emiteffect+traileffect psuedo-fields), for reliable emissions that are not framerate dependant (emitted forwards by default...
particles: rewrote 'sky' surface emittance. can now emit from submodels too.
particles: be more verbose about unknown mode keywords, instead of silent.
server: add basic misc_model emulation, for mods that don't implement one.
quake2: better r1q2 compat.
renderer: rework mindist+maxdist, should be more consistent as well as more reliable with orthographic matricies. has actual VF_ enumerations now.
sound: fix CF_FOLLOW to not crash, and work with openal.
client: 'cl_loopbackprotocol nq' now uses appropriate protocol extensions.
fs: try using /usr/share/games/foo by default, if it exists.
server: uncap drate if unspecified, do not fall back on rate.
