[Feature] More CartyParty Carts

[CameronWoof]

So, currently, if you get reassigned to a new job, it can actually be impossible to get your hands on the PDA cart for your job. This patch adds four more cartridges (Genetics, Janitor, Mechanic, and Quartermaster) to the CartyParty vendor, so that those are more attainable.

I consider these of minimal risk. The QM cartridge allows you to see but not approve or delete order requests and the order history, but that's not all that much.
