New auth system is going online; You will be logged out

Note: Nemmy will automatically upgrade your account by logging you out. Yeah I know it's not a pretty solution but it should work.

The backend is done, so everything that worked before should work now + some features using the new system.

New feautres:

• Account copy

Works by adding a new account with the same username as one you already added but with a different instance

• Instance hot-swap (

In the user menu there's a new dropdown on the instsance name where you can change the instance in real time

• New default instance

The default instance has been changed to lemmy.ml due to the massive downtimes on lemmy.world.

This does not affect you if you're logged in, which will override the default instance
