    selectionbar: Don't Pause machines that aren't running
    
    The "Pause" action maps to libvirt's "save" functionality, which
    consists of the process of taking a running guest and saving its
    memory state to a file[0].
    
    In doing so, pausing a non-running machine is useless and would
    trigger a "Pausing $VM_NAME failed" warning.

    Resolves #139
