added arrow navigation
completes #42 (closed)
works in my dev env. probably pretty overengineered, but technically it's made so that you could easily add other shortcuts later. I personally would use 4-wide tabs, but to conform to the existing code style, I made idents two-wide spaces.
Also, I made a Vagrantfile for this project, so it can be deployed quicker, easier & without cluttering the local env - would that be something I should get merged too?
