Version 2.5.1

Fixed various bugs in the handling of the MariaDB database in Oracle mode. Prefer to turn OFF the "Strict ODBC" handling in the general SQL settings for this database type, as the replacement SQL's work better for this database:

• Columns and other attributes of tables in other schema's can be discovered than just the currently active database schema.
• All database types are tested and some minor bugs in the handling of 'text' and 'longtext' columns have been fixed.
