v0.8.1a: various bugfixes:

- warlocks not playing debuff sound if hero is already debuffed
- various small logic errors with ring of wealth
- wand of warding incorrectly refusing to place a new ward with 1 energy left
- runes appearing on top of each other in runestone rooms
- particles on item sprites being visible when the sprite isn't
