Implement Login

[Cadair]

As an alternative to providing an access token we should allow specification of a username and password. In addition to this we should auto-detect the homeserver address using well-known.

Hey Cadair,

Im using your project with great joy! I saw you wanted this, so i wrote a simple python code to get the access_token from just the fulluser name and the password from a user.

I'm going to try to implement this in your code, but im not that good with python

Thanks for starting working on this! You can also use things in matrix-nio (https://matrix-nio.readthedocs.io/en/latest/nio.html#id1) to help process matrix events and stuff.

+1 I would really like this feature as it won't require an additional matrix client only for the purpose of octoprint notifications
