add mtui

[BuckarooBanzay]

this adds the mtui web interface on https://pandorabox.io/ui/

Demo here: https://test.pandorabox.io/ui/ (feel free to pentest that:)
Source: https://github.com/minetest-go/mtui

Currently it allows players to:

• Log in (via password or tan)
• Check their privs
• Check and compose mails
• Reset their password
• Send commands to ingame
• See the online players and some infos about them (only for those with ban priv)

This project aims to make the following obsolete:

• Webmail: https://github.com/minetest-mail/mail (has feature-parity)
• Auth-proxy: https://github.com/minetest-auth-proxy/auth_proxy_app (needs some changes to the mediawiki plugin)

Maybe even the beerchat-proxy in its current form some day (see #699)

I missed the party, but 👍 from me too, it's already an improvement to webmail, and it can only get better :)

• Reset their password

Looks like only changing password, unless I'm missing something.

Started to work fully only a few hours ago, the mod wasn't http-whitelisted :/

Yeah, for the moment, password-management and maybe some kind of 2fa/otp is planned though
