The registration fallback is broken and unspecced. This removes it
since there is no plan to spec it.
Note that this does not modify the login fallback code.
* Don't show the login forms if we're currently logging in with a
password or a token.
* Submit directly the SSO login form, showing only a spinner to the
user, in order to eliminate from the clunkiness of SSO through this
fallback.
* Clean up the CSS for the fallback login form
I was finding this hard to work with, so simplify a bunch of things. Each
flow is now a form inside a div of class login_flow.
The login_flow class now has a fixed width, as that looks much better than each
flow having a differnt width.
* Support m.login.sso
MSC1721 renames m.login.cas to m.login.sso. This implements the change
(retaining support for m.login.cas for older clients).
* changelog
The script recaptcha_ajax.js contains minified non-free code which
we probably cannot redistribute. Since it talks to Google servers
anyway, it is better to just download it from Google directly instead
of shipping it.
This fixes#1932.
This is because otherwise it won't get picked up by python packaging.
This also fixes the problem where the "static" folder was found if
synapse wasn't started from that directory.
