Small routine patch: employees can now be reassigned to a first iteration of the order packaging role. Earning experience in packaging will make them move faster in that role and add an extra bonus product to the order per two levels up to a cap.

Changelog:
- Employees can now be assigned to Order Packaging. Employees won’t use tables but for now will instead roam around taking items in their order box and carrying them to placed pickup points so ordering tables are left free for players. If possible they will always prioritize taking products from storage, then store.

- Implemented three new statistics/leveling for employees: technician, ordering and manufacturing. Manufacturing isn’t implemented yet but it was something very convenient to do now.

- Modified the employee’s tab interface to reflect all the changes above: a new bar of stars for each new competence. Already hired employees new values (technician, ordering and manufacturing) will be an average value calculated considering the old levels: cashier, restock, storage and security.

- Cashier employees will now check out several products at a time depending on their level. They incrementally earn experience slower from now on though.

- Due to the new addition of the technician role, furniture and devices can now also break in difficulty 0. There should be an average of 2 broken devices per day on difficulty 0 up to around 8-10 on difficulty 10. Earning experience will make technicians move and repair faster.

- Fixed not being able to be place lights on the ceiling of the Order Packaging department.

- Fixed NPCs yelling twice when slipping over a patch of water.
