Updated to electron 1.8.2

This tutorial looked like exactly what i wanted, except that it didn't work out of the box. I kept track of changes as I went and now it's up to date. Each step of the way also has a tag on my repo, although I don't think I can push to tags. In case you want to edit the tags on your repo, here are the references I have from running $ git show-ref --tags
