I ported dirt_man and sand_man over to mobkit.
While I was at it, I added a simple, but interesting behavior.
Dirt men like dirt, sand men like desert sand.
If they see what they like lying on the ground (as an item) they will go and get it (pick it up)
Also, if they are chasing you (and you havnt made them angry yet by hitting them) there is a chance that they will be distracted by you throwing the item that they like on the ground. If you have it, you might as well try. Punching them makes them really angry, and they will then not be distracted by your little presents
When killed, they will drop anything that they have picked up, plus the regular drop of a few dirt or sand.
