Equipment changes, see extended

Fixed an issue where attributes weren't being removed when unequipping
items.

EquipmentList and ApperaranceList are currently broken and will cause
crashes when modified, thus when equipping an item in any way will cause
a crash.  Expect a fix for that from Treeku shortly.
Fixed some corpses not despawning

- For test purposes, NPC respawn has been activated now
- Fixed double respawn issue
