    Support to send DTMFs from anywhere in the main GUI.
    
    Formerly, when you were in call and wanted to send a DTMF, it was
    necessary to switch to dialpad and press the appropriate button.
    
    It is now possible to press any allowed key from anywhere in the main
    window when it has the focus. That way, the user does not have to
    constantly switch between the dialpad and the roster when he wants
    to input DTMFs to a remote system.
