Bump jekyll

Wasn't working out of the box, but a Jekyll version bump seems to fix it. This bumps Ruby version and Gemfile.lock as well. It's looks good for me now, but it can probably use a sanity check!

@funionnn, you're welcome to take a look at the fork I maintain at https://github.com/erictheise/bloggy and monitor via https://gemnasium.com/erictheise/bloggy; I stripped out the unnecessary gems and keep it minimally up-to-date with dependency releases and security issues such as the recent nokogiri vulnerability. No active development as I don't believe that the bloggy approach is really viable anymore.

@erictheise Thanks! I'm using this because I've got a project at work that Jekyll meets my requirements for really well, except I need Google auth on it. This approach actually works fine without the gem dependency though since once the files are all set up, all you really need is the rake task. /shrug
