Add SSO/SAML support
Greetings.
When users are trying to log-in on the homeserver I moderate (https://matrix.tedomum.net
), the app does not react accordingly and falls back on the default homeserver (tested on the Android app as well as on the Web one).
We are currently using the SSO/SAML component of the Matrix spec available here: https://matrix.org/docs/spec/client_server/r0.5.0#sso-client-login
