Added `npm bin`, aliased npm start to webpack-dev-server
Added `npm bin`, aliased npm start to webpack-dev-server

This adds `npm bin` to reference the location of scripts, so as to guarantee
that the same versions of `eslint`, `webpack`, etc. are used by the npm
scripts.

Additionally, I've aliased `npm start` to `npm run dev`, just so it's a little
less to type :)
