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

- territories reworked, fixed territories can now be defined in the Territory.xml, factional headquarter stations generate territories as well, controlled planets generate territories based on their radius (territories not announced to players yet, got side tracked by couple mission fixes)
- Mission HUD sync fixed for missions with multiple players (only first player in the mission saw the mission objectives)
- Mission audio synced for all players in the mission (sounds will play for players that are further away from others)

experimental fix to mission objective screens for multi-player missions (only first player is seeing the objectives for some reason)

- NPC reputation reset on faction creation is done only once per faction founder

- Configurable option to disable one specific offer type while allowing others
- New economy config variable for blacklisted planet generator id's, if configured, planets with these Id's won't generate economy trade stations with /npc economy generate command

- New Offer contract type added
- Offers can appear on NPC trade stations
- Players can boost their reputation with other NPC factions, boost economy and military power of the faction holding the station and possibly buy a wreckage position
- New config variables added to Economy.xml allowing to disable/enable offers and set price modifiers
