BogOfGold Database Config Autodection of MySQL

[Dynamic-Gravity]

On a fresh install of BogOfGold and setting the database type to mysql the config will default to version 3 which will result in the tables of the database being created but unable to flush.

Error:

Per #141 (comment) changing the config type to version 8 seems to resolve this error.
