Removed the barely implemented sleeping and resting states of silicons (doesn't make sense anyway and probably wasn't intentionally existent). Also cleaned up powersink code to enforce its mode and all variables affected
Fixes talisman items not fully removing selves when used
Shards are dangerous, Take Two!
-Shards cut your hand if you try to attack with one and you are not wearing any gloves.
-Adds a sound to attacking grilles with shards.
-Changed the randomized force into throwforce.

Should be less favourable to break down grilles with shards now.

Changelings Scaling to Server Population

Adds scaling of number of changelings to server's population if TRAITOR_SCALING is enabled in the server config.

pop/6 during Changeling mode
pop/18 during TraitorChan mode
(For reference, Traitor uses pop/5)
Increased changeling_scaling_coeff to 8 after further thought.
