added a couple extra effects to r_particledesc high
try and solve the trailparticles madness once and for all by autodetecting which set of arguments is used.
fix some annoyances with menuqc.
rebuild fs cache when doing vid_restart, to avoid insane reload times.
add profiling support.
qcc: be more permissive with {a,b,} in array definitions.
tweaked logfrag builtin to not loose frags quite so easily. should be more robust now. Whether tools agree or not is a different matter... but there's always the possibility that it'll just work.
