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
