/*QUAKED spawnfunc_func_fourier (0 .5 .8) ?
Brush model that moves in a pattern of added up sine waves, can be used e.g. for circular motions.
netname: list of <frequencymultiplier> <phase> <x> <y> <z> quadruples, separated by spaces; note that phase 0 represents a sine wave, and phase 0.25 a cosine wave (by default, it uses 1 0 0 0 1, to match func_bobbing's defaults
speed: how long one cycle of frequency multiplier 1 in seconds (default 4)
height: amplitude modifier (default 32)
phase: cycle timing adjustment (0-1 as a fraction of the cycle, default 0)
noise: path/name of looping .wav file to play.
dmg: Do this mutch dmg every .dmgtime intervall when blocked
dmgtime: See above.
