node restarter in gulp specifically for monument based web apps

Gulpfile.js

// NOTE: I previously suggested doing this through Grunt, but had plenty of problems with
// my set up. Grunt did some weird things with scope, and I ended up using nodemon. This
// setup is now using Gulp. It works exactly how I expect it to and is WAY more concise.
