when the fixed encounter spawns, BuiltBy is set to 0

fix for NoDefaultSellGrids not being taken into account by free ports during free port creation

command to show dynamic economy modifiers /npc economy dynamic

dynamic amounts for sale and purchase on NPC trade stations and ships based on the dynamic economy modifiers

methods selecting prefabs for spawning will select backups in cases where npc faction definition has entries, but not of the required type/size

minor hotfix for a method which selects valid space prefabs for cases where NPC packs might not have any prefabs of the required size

- PlanetaryHoldings.xml structure updated (the update will happen automatically on load, your configs will not be lost).
- DynamicConquests setting changed to PlanetaryConquests & FreePortConquests, works the same way as before, but planetary and free port sieges can be disabled/enabled separately.
- Free Ports can have no profit faction,
- Free Port sieges are no longer enabled/disabled by the FreePortOfferModifier attribute in the economy config, they use the FreePortConquests in the PlanetaryHoldings.xml.
- Free Ports can be set as indestructible with the <Indestructible>true</Indestructible> in the economy station entry in the Economy.xml.
- If Free Ports are set as indestructible, they will not be destroyed if upkeep is not paid for prolonged period, instead, the player profit faction is removed.

- planetary blacklist can blacklist planets not only by the generator definition subtype, but also by entity id. Keep in mind, that entity id should be used only if you have several planets with the same subtype (say, 5 Moons) and you want to blacklist only some of them.
- can be used in economy configuration, mission configuration, spawn triggers and planetary holding config

updated target range checks for station behaviour

ok, now they can, forgot to make the stations to actually lock targets :D
