* 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
* The main loader script has been updated to generate the list of files
it needs to load automatically. As a consequence, files that contained
manually-maintained lists of scripts have been removed, and definition
directories have been renamed accordingly.
* PostgreSQL extension loading and configuration has been moved to a
separate script to be loaded automatically in the main transaction.
* Data and function definition scripts that had the -data or -functions
suffix have been renamed (the suffix is unnecessary).
* Unit tests have been reorganised to follow the definition's structure.
* Documentation has been improved
* Added in-base logging through a foreign data wrapper, which is only
possible using PostgreSQL 9.1
* Renamed database-related configuration files to indicate that they are
samples, and added the "real" names to the Git ignore list. Server
distribution modified accordingly.
* Removed PL/PgSQL registration (it was only necessary on 8.4)
* Added pgTAP SQL definitions and a script which will (hopefully) be
executed by the build system after the main Java build in order to
execute database unit tests. The script supports both admin- and user-
level testing. I also added a few tests to make sure the testing framework
actually runs them.
* Added documentation about the database definitions structure
