+ - Added db_set_charset() support.
+ - Added _optimize_table() support for the :doc:`Database Utility Class <database/utilities>` (rebuilds table indexes).
+ - Added a constructor to the DB_result class and moved all driver-specific properties and logic out of the base DB_driver class to allow better abstraction.
