Separate dependencies from JS/CSS code about serverlessbydesign

I like that everything needed to use the tool was available locally. I do a lot of programming on trains/buses with intermittent internet.

@fblecha @rts-rob I'm not necessarily suggesting to use CDNs for external libraries. I am suggesting to remove them from the repo and use a proper dependency management tool.
This way, you'd only install dependencies once at clone-time. Also, we'll be able to update libs versions over time without manually copying huge files.

I agree, the reason I included the source JS/CSS files for the dependacies was that I still wanted people to be able to clone the repo and start using it locally, without having to use a too such as npm/bower to install the dependencies.

PR #2 adds in browserify which I suggest is a good middle ground. If we upload bundle.js (as the PR does) then it's ready to run locally without any additional commands as soon as the user clones it, but we still get the modularity of browserify (which I used to avoid name collisions between the engines).
