From d947eba0bdaf9d86401fdcba9e97706905cacf9d Mon Sep 17 00:00:00 2001

Subject: Multiple DB Forge improvements  - Replaced driver methods
 _create_database(), _drop_database(), _drop_table() and _rename_table() with
 properties  - Added defaults for the above mentioned platform-specific
 queries, so that not all drivers need to define them  - Improved support for
 the SQLite, ODBC and PDO drivers
