Delivery missions & Food Delivery missions no longer show subtypes instead of actual names of the items

audio balancing for drone voicelines

Unique naming, now not "more or less" but definitely

- faction definition could be made with a specific player faction in mind, which is allied to the NPC faction

rep change fixes + small cleanup of redundant code

- demo economy station from the first economy config generation removed, it was there to show how economy stations look long before /economy generate command existed

- when player reconnects, the mission had a different name after restoration from persistence, I forgot that I was using the name to distinguish combat missions with the /npc mission show gps command, thus it stopped working. Now it should be fixed.

- ENC name replacement for mission NPC fixed
- /npc mission show gps, command fixed, possible null pointer exception
