Unload rotting items, stop hauling ghosts

Colonists will now quickly unload if they have items that are about to rot.

Colonists will no longer try to haul ghost items.

Various other fixes, notably with the tweener, heavy items and a bunch of others.

Kleptomania fix

• Fixes kleptomania (pawns wouldn't unload reliably)
• Simple Sidearms compatibility patch
• Combat Extended no-conflict patch.

B18 - People haul chunks?!

Fixed an error with chunk hauling behaviour. Added a few checks to prevent needless inventory shoving and hauling.

Initial release

Colonists will gather stuff in their inventory, then haul it all to a stockpile.

This hauling mod will greatly increase hauling efficiency, because pawns can now carry more than one gun or t-shirt. Those smart and intelligent colonists can use their inventory! You gotta see it to believe it.
