Travis Ralston ccce6c196d Specify how capabilities work in the c2s API
Original proposals:
* https://github.com/matrix-org/matrix-doc/pull/1753
* https://github.com/matrix-org/matrix-doc/pull/1804

Implementation proof:
* https://github.com/matrix-org/synapse/pull/4472
* https://github.com/matrix-org/matrix-js-sdk/pull/830

There is one change to MSC1753 which is included in this commit. MSC1804 remains unchanged. In the original proposal, the change password capability being present was an indication that password changes were possible. It was found that this doesn't really communicate the state very well to clients in that lack of a capability (or a 404, etc) would mean that users would erroneously not be able to change their passwords. A simple boolean flag was added to assist clients in detecting this capability.
