Game updates improvements

* 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
