Convert to jekyll

Fixes #14

Sorry I'm just now getting to this. Here's my review.

• The Gemfile and Gemfile.lock files aren't needed. Jekyll will work just fine without them, and IMO only complicates the build process. I don't think GitHub Pages takes them into account, either.
• Quotes are missing for the links inside apps-mobile.yml.
• Are any of the plugins in _config.yml being used?
• I don't have any of the files excluded in _config.yml. I believe the entire section can be safely removed.
• The 404 page could be better. How about linking to or redirecting to the homepage?

Everything else looks fine to me. I got no errors. Some differences from the current site (not sure if you're aware):

• The current site has the Android link removed. This version still has it.
• Some of the items under "Community Apps" have a by tagline and other information in the live version. This version doesn't.

With the most important parts converted to Jekyll, making a new design with the site content should be a lot easier now.

These are all of the things that I noticed. Glad that you took the time to do this!
