Security Level in http

The security level now ensures the application started by the Genero Desktop Client is the one you started.

When connecting directly to the runtime system, some tests are done, depending on the Security level, to accept the connection.

When connecting via Application Server, the security level was ignored. Now, when using GAS 2.20, GDC 2.20 and DVM 2.20, the security level is also managed to be sure the application you have on GDC is the one you started.
