This commit introduces a new BeginRequestType enum which gets passed to the 'reset' signal to specify whether a username should be provided to the begin() method and changes the loginDialog to comply. Currently, the signal only ever gets emitted with AuthPrompt.BeginRequestType.PROVIDE_USERNAME but that will change in the future when providing smartcard support. https://bugzilla.gnome.org/show_bug.cgi?id=683437
