overhaul website

@timothyfcook @tenkabuto @steveklabnik @jkwade @veganstraightedge @ityonemo et al.

I redid the website. I went with a very simple, straightforward design, using Jekyll for templating. The content should be more or less complete.

You can find a staging version here (once DNS propagates):

Any objections to publishing this at http://www.opencompany.biz/? Any tweaks or other suggestions?
