Login-feature for up.tilde.green

it'd fall back to the OIDC assuming

By this I mean it'd try to redirect the user to the OIDC login, but only if they click the login button, which can only happen if that check doesn't match because they need to be from a web browser to be able to click it.

Great, and my implementation that's based on yours (when I finish writing it), will also use ISC.

I made a file called auth-LICENSE with our names (haven't committed it to git, I plan on doing commits when I have part of it working), but I'm not sure if I should just put the names below Andreas Hackl's name in the normal LICENSE, I think that'd make more sense, probably?
