According the the openapi spec, examples for responses and schemas should be
raw objects rather than being json strings. (It's unclear what non-json
examples should look like...).
The swagger UI used to support json strings, but no longer does. In short,
let's turn the json strings into their raw formats.
We're licensing hte spec under ASLv2. Add the LICENSE file, and add the
short-form to as much of the source as is practical right now (adding it to
json source is a massive pita).
* Use the terminology 'login type' everywhere instead of mixing up 'stage type'
and 'login type'
* Don't have a separate 'APIs using the User-Interactive Authentication
mechanism' section, because (a) it doesn't make much sense to organise the
APIs this way, and (b) it was a set of lies anyway.
* Move '/account/password' definition into registration.yaml so that register
and password can share a section in the spec; remove duplicate doc for
/password.
* Write some words on using 3pids for /login
