* Added a set of tables which define game updates and their targets. These definitions replace the old enumerate type. Added a set of triggers which automatically create specific update tables, insert missing entries, etc... when game update types are being manipulated. * Removed manual insertion of game updates from empire creation function and universe generator. * Added registration of core update targets (i.e. planets and empires), updated all existing game update processing functions and added type registrations * Created Maven project for game updates control components, moved existing components from the -simple project, rewritten most of what they contained, added new components for server-side update batch processing
