MySQL#init not invoked anywhere, missing Table Definitions

Hello!

A user of your plugin messaged me today telling me that the plugin doesn't seem to create tables in a fresh database anymore. I had a look at the sourcecode and noticed that `MySQL#init` isn't used at all. I added an invocation to `MySQL#connect` after the connection assignment, as I think this was intended behaviour.

Just let me know if I misinterpreted your control flow and that method is actually being called somewhere else.
