Replaced HandleCharacterSet*() with HandleCharacterMovement()

This new method rolls three otherwise similar methods together. There is
still a conditional which handles room movements separately, but it's much
smoother, and PumpPacketProximity is utilized much more.

I've also added a stub for graphical attack data via
HandleCharacterAttack()
