Issue stemming from lack of ability to modify DB ports in installer #28

As the title suggests, the inability to change the DB port for the panel and the store prevent the app from being used by GSPs that change their DB ports for security. Adding the feature to change the port used would fix this issue.
Expected behaviour: Webpanel connects to DB on port 3306.
Actual behaviour: Webpanel errors due to DB running on other port.
