title: Whitelist extensions for Google Chromium
body: <p>I'm trying to deploy a standalone build of Chromium to run a web app on customer machines which can't have full Chrome installed on them. With a recent build of Chromium 20, when running in <code>--single-process</code> mode Chromium is being crashed by the Skype extension, so I'd like to disable that extension. I'm also bundling my own pre-installed extension, so I don't want to fully disable all extensions.</p>
  
  <p>Ideally I would be able to blacklist all extensions just for my install of Chromium, and whitelist just my extension. I'd like to do this in a way which doesn't affect other installs of Chrome on the machine. I'm installing my extension through <code>master_preferences</code>, can I set a whitelist there too?</p>
