🌟 New: Adds basic server boilerplate that supports watching

[aendra-rininsland]

This adds a really basic Koa 2 app that serves out the dist/ folder on port 5555 upon $ npm run server.

If NODE_ENV is set to development, it uses BrowserSync to monitor the dist/ folder, and uses a customised version of the gulp watch task (gulp watch-server) to monitor the client/ folder, serving out built versions of client/ upon change.

It also adds a Procfile, as well as updates package.json to build client/ and transpile server/ during the npm postinstall hook. This enables it to be easily pushed to Heroku. 🎉

Lastly, it consolidates the two optionalDependency sections of package.json that were added in #19.

Now we need port the build-pages and html task from gulp to the koa app: i.e get server to create the HTML pages, binding the contents of /config to the the /views and something to save them as static

Have pushed updated version that replaces practically all Gulp functionality with a Koa 2 server.

Still @TODO before merging:

• Create individual path fork for rev function; remove this block
• Make rev function work with CSS (images, fonts)
• Benchmark in production mode
• Tidy up package.json; update scripts section
• Rebase against 🌟 New: Adds ability to load from g-ui #29 once merged
• Write E2E tests, unit tests
• Move test running to package.json
• Remove Gulpfile, Gulp-related dependencies
• Replace dep on Bumped bower version to ~1.7.9 eugeneware/debowerify#85 once merged

This is hopelessly outdated and won't ever make it into Starter Kit given the project's roadmap. Leaving branch in case someone wishes to port it elsewhere, but closing otherwise.
