    plugin.rst: Move import below plugin information fields
    
    The RestructuredText plugin depends on python's docutils, which is not
    a core kupfer dependency. We absolutely must import it lower down, so
    that the plugin will still show in the UI (with a good explanation) if
    docutils is not installed.
