* Rip out half-implemented m.login.saml2 support This was implemented in an odd way that left most of the work to the client, in a way that I really didn't understand. It's going to be a pain to maintain, so let's start by ripping it out. * drop undocumented dependency on dateutil It turns out we were relying on dateutil being pulled in transitively by pysaml2. There's no need for that bloat.
