Mysql SSL errors - add useSSL config option

[TheoRetisch1]

The plugin causes the following error in the log all the time:
Establishing SSL connection without server's identity verification is not recommended. According to MySQL requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Unfortunalty the plugin doesn't load if one tries to edit the string: jdbc:mysql://localhost/minecraft?useSSL=false
It would be awesome, if you could add an useSSL: false option in the config to stop the console spamming.

Cool plugin btw 👍
