Bugfixes:

Projectiles now last 50 ticks then dissipate. 
- This is to prevent people from firing these into space causing large amounts of projectiles to be processed needlessly.

Re-coded the cremator's cremate(), it should not lock up any more.

Removed a duplicate attackby() in pill bottles. They should now be able to pick up all pills on a tile properly.
- Fixes Issue 490
- Thanks to Zelacks for pointing this out.

Handcuffed mobs who are being dragged by another player can now move when the puller is stunned or paralysed.

Ashes are now decal/cleanable and can be mopped up by janitors
