Link client and website databases

[suhbruh]

Link in-game client registration of an account with website account registration/login. Merge into one mariadb.
Users should be required to verify emails if they want to access website as a logged in user. No priority on this because I am unsure when the website will be near completion.

Eventually, I would like an additional feature to prevent account creation abuse: If an account is created within the client, the account has to be verified on the website within 24 hours to remain active. If not, the client login gives an error that the account has not been verified. But, first we need a website that is ready for beta release.
