Using offline Material icons and Roboto font in Electron app

It wasn’t so hard afterall. First install the npm packages

npm install material-design-icons --save
npm install typeface-roboto --save

Then go to main.js and import them

import 'material-design-icons/iconfont/material-icons.css'
import 'typeface-roboto/index.css'

Tada! done. Our font and icons are now local!
