* Added a system that allows "dirty" tests to be written. These tests
actually need to change the database, so a temporary test database must
be created to run them.
* 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 defs.uoc_resources() set of functions which create or update
basic resources.
* Added defs.uoc_natural_resources() set of functions which create or
update natural resources.
* Added base classes for all importable data. These new classes should
be used for all future loaders; all existing loaders that are modified
should be updated.
* I18N loader rewritten to make use of the new base classes. External
strings are now read using the XML data file's path as the base
directory.
* Updated all external I18N definitions and moved the existing files
around in an attempt to make the data directory somewhat more livable.
* Added dependency management entry for the server's main package to the
root project, updated server distribution package accordingly. Added
dependency on the server's main package to the server's testing package.
* 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
