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.
This should have little/no gameplay effect right now, just paving the
way for directional lights.
Replaced handle_rotation() on buckly things with this.

Makes reinforced glass a subtype of glass, cleans up window creation copypasta.
Cleaned up window initialization leaking outside of the window constructor.
Removes unnecessary init_dir var from windows.
Committing this early to allow pete to commit something involving the .dme file which would probably conflict otherwise.
