- Mission persistence fix, reconnecting players were able to break missions with multiple people, system created another instance of the same mission by mistake
- Unique naming (more or less), subsequent spawns check previously living NPCs and alters names by adding suffixes, if another active NPC with the same name exists. This should prevent mission steps and missions bleeding through into each other.

Altered the voiceline timers for computer voices, so it doesn't spam the same voicetime too much.

- Drone computer voice-lines (6 voice types)
- new attribute for marked drone ships (isDrone attribute) to pick the computer voice type (missing attribute means silent drone)
- reworked pilot voices (code clean-up and streamlined approach if I would want to add more voice types in the future)

to check which player faction has which free ports, players can use /npc info <faction tag> command

- New Free Port economy mechanics added
- Player factions are able to buy trade station licenses and establish new trade stations with them as a profiting faction. Getting some percentage of the cash being spent on that station into their faction bank (20% by default)
- New siege mission type, where NPC faction can declare siege on free port type station, when such siege is finished the player faction finishing the siege becomes the new profiting faction, and the NPC faction declaring the siege will become the controlling faction
- new commands /npc freeport (to spawn the free port) & /npc salt (to generate new encoding string for the free port licenses)
- new config attributes for the Economy configuration FreePortOfferModifier (which affects the price of the free port license offers and disables free ports completely when set to 0) and FreePortPercentage which is a number between 0 -> 1, and decides the profit from all sales on the free port, which then goes to the player faction co-owning it

fixed a weird fringe case where mission generation could freeze the game process when there was nothing on the map (no planets, no asteroids, no grids) as spread of entities was used to seed how far global mission positions could go from the center.

missing null check

fixed wrong territory sort

Territory announcements when players enter new territory, or leave territory completely

hotfix for spawning, one method returned "None" instead of null, leading to wrong condition check
