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
CORE: added refreshSession(sess) method

  It's for case, when user join identities and we want

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.

RPC: support embedded tomcat7 to run Perun locally

- You can now run Perun locally by "mvn tomcat7:run-war" in /perun-rpc folder.
- You still need configuration files in /etc/perun (e.g. taken from devel).
- If you don't use own DB, start SSH tunnel to devel DB before running RPC.

- In order to actually get response from Perun (other than exception) you must
  setup Apache web server to provide (or fake) authz in AJP headers and
  it must rewrite external http request to internal ajp request.

  Example Apache configuration file is on internal redmine wiki.

- HTTP and AJP ports are both started (did't find way to disable unnecessary HTTP port).
  But you will never get proper response from HTTP port since it will
  be missing AJP header for authentication provided by Apache.
RPC: converted spaces to tabs
