DO NOT MERGE SUCKERS!!!

This is not done at all, but wanted to stop here if anyone hated the direction. The idea would be to handle everything in the json files. For example, _date.json would have a current property that would have date, location, speakers, etc. Then I started making some jade partials for speakers, nav, etc. I'm not sold on jade, it looks really pretty, but I'm so used to regular old html that I get hung up on it.

I didn't plan on changing any of the css, markup(besides moving to jade), or js in the PR just because I wanted to get us using harp rather than try to rewrite the entire site in one go. I think this will make it easier as we can just update the _data.json file and move the current object to the past-events.

Next steps once this is finished is to move over to using browserify and stylus, and change the markup structure. We could probably get some folks to help us out with that part.
