Add rings that can cast spells to the game.

These function like low-power rods, since they regernerate spell points much slower and can cast fewer times before running out.
The list of spells is a lot more geared toward utility and infrequently-cast spells, such as summon <elemental> and dark vision for that reason.
Currently set to be pretty rare. If it turns out these should really be more common than rods, it can be done.
