    html-preview: add shortcut for html preview
    
    This adds an ctrl+alt+p shortcut like we used to have a long
    time ago. However, due to a bug in the shortcut controller
    dispatch in libdazzle, it does not current activate unless it
    is set to global (which we do not want).
    
    We'll have fixes coming to libdazzle shortly.
    
    Additionally, it would be nice to register the command with
    the shortcut manager so that we can get automated UI in the
    shortcuts window, but we need to figure out how to do that
    from Python first.
