make passphrase non editable while validating it
Allow server to return several revocations at once.

If there is more than one revocation pending for a contact, the server
will now return as many revoctaions as will fit in the error message.

Two CLI fixes.

1) After the change to late signing, a typo meant that the client would
   exit when sending a message.

2) Drafts created in the UI don't always have a destination contact set
   so a statefile that was used in both the GUI and CLI could end up
   crashing the UI.

Time to start writing unittests of the CLI as well as the GUI.
