Enemy Loadout Generation

Modified zone generator to scale the radius and mass of a zone according to galaxy density
Added loadout generator which procedurally generates ships and turrets
Generating 3 randomized ships in each occupied zone
Fixed DatabaseCache.GetAll for parent types
Fixed wormhole traversal bug for returning to previous zone (ZoneRenderer subscriptions not being properly disposed)
