title: How to always allow Chrome plugins in command line
body: <p>I want to always allow my NPAPI plugin in Chrome. I find in page <code>"Chrome://plugins"</code>, there is a checkbox <code>"Always Allowed"</code> for each plugin.  </p>
  
  <p>Now I want to make one plugin <code>"Always Allowed"</code> without clicking that check box, so how can I achieve this? Is there any command arguments for this?</p>
