Editing index.html does not trigger a reload

Created by: whichsteveyp

I'd say this is pretty minor, but I noticed when I updated my index.html <title> it did not trigger a browser reload. I did however see it on manual refresh.

I also noticed that I wasn't exactly clear on how index.html maps to index.js, when I started digging through webpack.config.dev.js. I saw a few comments in there, while looking through it briefly to see if I could resolve this locally and perhaps send a PR. I'm extremely new to webpack, so I don't dig around in here too much yet (and I don't eject really either).

Thanks!
