+/*QUAKED func_pendulum (0 .5 .8) ?
+Solid entity that swings back and forth in an angular motion. Entity swings on the north-south direction by default (can be changed by using a different yaw angle).
+-------- KEYS --------
+speed: angle amount of the swinging
+freq: frequency (cycles per second) of the swinging (if unspecified, a physically "somewhat correct" value is calculated that matches Quake 3)
+phase: sets the start offset of the oscillation cycle. Values must be 0 < phase < 1. Any integer phase value is the same as no offset (default 0).
+noise: path/name of .wav or .ogg file to play. Use looping sounds only (e.g. sound/world/drone6.wav - See Notes).
+dmg: damage a player who gets crushed by it receives
+dmgtime: interval to apply dmg to a player who is s in the way
+message: death message when a player gets crushed
+message2: death message when someone gets pushed into this (default: "was thrown into a world of hurt by"). The # character is replaced by the attacker name if present (and it instead does not get appended to the end)
