1010 when .target is set. If not, this is hoe mutch to slow down/accelerate
1011 someting cought inside this trigger. (1=no change, 0,5 half speed rougthly each tic, 2 = doubble)
1013 radius : If set, act as a spherical device rather then a liniar one.
1015 falloff : 0 = none, 1 = liniar, 2 = inverted liniar
1017 -------- NOTES --------
1018 Use a brush textured with common/origin in the trigger entity to determine the origin of the force
1019 in directional and sperical mode. For damper/accelerator mode this is not nessesary (and has no effect).
