Do the blog thing on the Gaslight.co thing

**Warning: Do not merge!**

Ok, here's the deal: tumblr is hard. Markdown is awesome. GitHub is awesome. Rails is awesome.

I took the things that were not fun and combined them with the things that are. I built a "blog engine" from the files in the gaslight/posts repo. There are still things that need to be fixed:

- [x] comments
- [x] post title
- [ ] author name
- [ ] posted on
- [ ] tags
- [ ] search
- [ ] TESTS

To try this out:

1. Clone this repo. `git clone https://github.com/gaslight/gaslight.co.git && cd gaslight.co`
2. Check out this branch `git checkout blogger`
3. `bundle install`
4. Clone `posts` in to tmp/ `git clone https://github.com/gaslight/posts.git tmp/posts`.
5. `rails server`
6. `open http://localhost:3000/blog`
7. Profit!?
