Fix for GitHub save failing

[davekobrenski]

resolves jocelyn-stericker/hacklily#55, resolves jocelyn-stericker/hacklily#33

Saving to GitHub was failing due to process.env not being available on the client side. Adding a few lines to the webpack.config.js fixes this.

Also, I updated the README.md as the makefile doesn't exist, so the make serve command is outdated? I updated the readme with the commands that (I think) should be run instead. I should note that I was getting an error with yarn build but not with npm run build. The yarn error had something to do with the enhanced-resolve npm plugin and the normalize.css file in src.

Love your work on this, btw. Really nice and useful.

Hi, I'm also having trouble saving files, is there a reason preventing this fix to be applied? Thanks :)
