Adjusted the MF_changesprite function meant for light modding:
MF_changesprite( fixed, file, frame, direction )
fixed = the object's internal id
file = sprite filepath relative to the location of the executable, with file extension
frame = 0-2; one of the wobble frames
direction = 0-31; the animation "bank" which is adjusted. 0 = facing right, 8 = facing up, 16 = facing left, 24 = facing down
