Grilles and rods.

Grilles no longer return more rods than they were created from when destroyed (by method other than wirecutters).
Rods are now acquired from and returned to a pool.
Also adds a pre-broken grille for mapping, avoids the case where one might be able to destroy the same grille twice.
