Created by: clusterfack

-Improves become_mommi button for observers, gives an option of all the areas in which mommi spawners that are ready to spawn are located -Fixes a bug where mobs with a mind would not be transferred into a built mommi from a mommi spawner -Fixes a few typos -Removes the 'you have no lungs panic and tell a coder' message, since you can actually have no lungs now
