Amulet of Faith, mark I.

Amulets of faith have these effects:
- Piety gain is 1/3 faster.
- Gods that protect from harm are more likely to do so (your piety is 1/3rd
  higher for such checks).
- Xom piety walk is 1/3 faster.
- Xom is more likely to act.
- Removing the amulet leaches away some piety, but will never cause
  excommunication, or drop piety too close to excommunication.

Amulets auto-id if the player already has a religion, or when the player
acquires a religion while wearing the amulet.
