    libanjuta: Introduce execution modes to AnjutaCommandQueue
    
    Clients can now choose to execute their command queues automatically or
    manually. In automatic mode, commands are executed as soon as they are
    pushed. In manual mode, commands are pushed, but are only executed when
    explciitly asked.
