Journey to the Center of Hawkthorne (Game)

JttCoH is a fan-made game based on the show Community. It's been thriving at [/r/hawkthorne](http://www.reddit.com/r/hawkthorne) for quite awhile now, and recently celebrated its 2-year anniversary.

This is an ongoing pull request. There are a few unresolved issues.

1. The licensing system is complicated. The code is MIT, the art and audio assets are Creative Commons, as indicated in the [README](https://github.com/hawkthorne/hawkthorne-journey#license). And of course, some network owns the rights to the characters, so nobody knows what to make of the grey area there, although it's 2 years incident-free and show-creator-acclaimed, so <shrug>.
2. There are makefile changes that I've implemented as a patch, but would really like to port to the mainline code. That doesn't have to happen immediately, or in the scope of this ticket, but it ought to happen eventually for maintainability reasons.
3. It's unclear how well the test suite will work in a headless environment, and that it will run headlessly when being built on a graphically enabled machine. I think the former is *probably* a non-issue... part of the reasoning for it existing, seems to be as a sanity check on Travis CI. The latter, I have no idea.
