Computer Stuff (#3932)

This started out as just some stuff for cargo.
Then it grew.

Fixed tablets and laptops not working due to some changes in #3826 that caused some old ballast to haunt us.
Changed the beeping sound of the modular computers to respect the ambience sound preference.
Added a application that can be used to pay and verify that a cargo order has been received
Added a delivery pad to cargo and spawns one in the CTs and QMs lockers.

Further tweaks to tablets and device enrollment in general are incoming, but I dont want to bloat this pr any further.
(I dont like how the company/private device system is implemented right now; It should rather be based upon the hard disk than the device itself)

closes #3931
