Replaced wall_smash in simple_animal with environment_smash, because before, you either tables AND walls, or nothing. If set to 1, smash crate/locker/rack/table, 2 for wallsmash, 3 for rwall smash

Hostile mobs with environment smash will also unbuckle themselves by destroying whatever they're buckled to when angered.
