Started converting 'Acms\Core\Data\Db' from AdoDB to Aura.php. Also started working on the Install plugin.

Db::dbSelect and Db::dbFetch seem to be working, and most of the AllianceCMS is using the altered Db interfaces (no more straight Aura.Sql queries).

Still need to go through the code to make sure I've changed all references to straight Aura.Sql code to Db references.
