Database definition & tests organisation

Browse source 
* 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
