Terminal-like vending machines have been implemented in r5379. Part 2 has been
completed with 3 vending machine designs; part 1 still needs to be worked on;
part 3 sounds odd (maybe med-kit stands would make sense in dangerous
workplaces, but vending machines that casually sell ammo?. Then again, the FDRPG
universe is a little bit crazy...); part 4 has been worked around, as the dialog
triggered by type=32 immediately opens a trade screen through EveryTime code.
