GUI: Removed cross-site scripting hack for devel

- Cross-site scripting is no longer possible for development purpose.
  Use local Apache server and Tomcat or Jetty to run Perun locally.

- New JsonClient is not limited to standard timeout of 30s and
  waits for Apache timeout/response.

- Json(Post)Client now handles 401 and 500 responses as onError().
  For 500 also determine, if it was timeout (longer than 5 minutes).

- Removed unused stuff and properties, source format.
GUI: handle also 503 error for JsonClient

REGISTRAR: fill user to session if possible

- Fixed case when user join identity.

- Retrieval of form must always check, if user is known by ext source,
  and if yes, fill user in session.

- Creation of application must do the same so user is set to application.
  It would be paired on approval, but it's nicer for admins to see username
  rather than actor/extSource.
