    doc: Remove the part about installing Ghostscript on Windows.
    
    On Windows Ghostscript nowadays gets installed by the installer.
    No need for manual installation so we can remove the
    paragraphs about how to do that.
    Referenced in issue #257.
    
    Also mention pdf besides postscript as plug-ins that require
    Ghostscript.
