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
