title: electron/muon: require not defined in renderer
body: <p>I'm currently working on an IPFS/Ethereum dapp in Muon.
  Because i need Metamask i started with this Boilerplate: <a href="https://github.com/SwapyNetwork/electron-metamask-boilerplate" rel="nofollow noreferrer">https://github.com/SwapyNetwork/electron-metamask-boilerplate</a></p>
  
  <p>Everything is working fine so far.
  However i can not use require('anything') in the renderer process or in html script tags. (See below)</p>
  
  <p>There seems to be a problem with the boilerplate code but i can't find it.
  Or is node code in renderer not supported in Muon?</p>
  
  <p>My only change in testing is setting node-integration explicitly to true and
  inserting require('fs') in index.js. (i installed fs of course).</p>
  
  <p>I tried many different solutions from stackoverflow and other sites but couldn't find a solution yet.</p>
