Mob refactoring.

Updates Bump() code.
Intents now use constants.
Simple animals can now use languages without overriding say().
There is now a difference between being able to smash normal and reinforced walls.
Reworks simple_animal/attackby so that constructs don't need to override it simply to add damage resistance.
