Gameplay
Added a new service worker, the "Purchaser". He will automatically order random items for you every 2 minutes. He will absolutely blast your wallet if you aren't prepared!

Added a "Daily Individual Ware Price Adjuster" for unlocked wares. Usually it will result in an increase in sell price, but it might also dip into the negative.
Added a new hotkey and inventory item, the "Animal Snack". Shoot this at a red glowing animal to stop them from either taking a dump in the store or sabotaging your wares. It containts 200 charges which can be refilled at the computer, under the "special" section.

Decorations and lights can now be placed upstairs when unlocked
Bugs
Fixed a bug where the pathing of AI didn't build correctly, leading to customers sometimes not being able to find a path to the shelves and leaving early.
