Wedding Ring a defense mod

Live players already had wedding rings in their defense mod list. Let's
leave it as a defense mod that does nothing.
Resist Ring Durability setting

Defaults to FALSE. Resist rings won't lose durability unless the setting
is on.
Resist Rings no charge description if no durability

If Resist Rings aren't losing durability, they won't have charges listed
in their description.
