core (xmpp): server certificate validation: XMPP server certificate is now checked, and connection is refused (by default) if it's not valid. Certificate check can be disabled in the new parameter "Configuration/check_certificate". If certificate checking is disabled, a warning note is sent on every new connection. Twisted and Wokkel are temporarly monkey patched in sat.core.tls_patches module, until modifications are merged upstream.
