Merge lp:~nataliabidart/ubuntu-sso-client/stable-3-0-update-2.99.3 into lp:ubuntu-sso-client/stable-3-0

[Natalia Bidart]

[ Natalia B. Bidart <email address hidden> ]
  - Skipping failing tests (see bug #920591).
  - Make webclient an installable module.
  - Make the GTK UI a separated executable script (LP: #917373).

[ Diego Sarmentero <email address hidden> ]
  - Delete signal removal to keep listening to network state changes (LP: #920591).

[ Alejandro J. Cura <email address hidden> ]
  - Restfulclient calls are now POST; response.headers are now case-insensitive
  dicts; OAuth timestamp sync with the server (LP: #916034).

[ Manuel de la Pena <email address hidden> ]
  - Add the possibility to skip the lint checks on windows when passing the
  /skip-lint parameter to run-tests.bat (LP: #918248).

[Alejandro J. Cura (alecu)]

Branch looks good, tested IRL.

review: Approve
