Add back in sounds on monster deaths from spells.  Closes #1630.
Adjust 'when drunk' to 'when quaffed' for pedants.  Closes #1635.
Remove ancient skeletons from the closet and move the iron spike to a tval with a name so HTML screendumps don't fail when they try to load back the pref file (this happens because the game writes 'unknown' as the tval and can't read that back in again).
Move HTML screenshot code to use native save boxes where available.
