Attaching Items

General placeholder:

Use bind to bind entities to other entities, eg, a flame to a moveable candle; a notice on a door; a purse to a guard's belt.

Use bindToJoint in addition to bind on AI's to specify which joint of the body to attach to.

Use bindOrientated in addition to bind so the bound item doesn't turn with the item it is bound to but remains pointing in its start orientation.

Use def_attach1 for weapons TODO

Use def_head to attach heads TODO
