Several problems with paths

Consolidating #7 for a central issue on issues with links...

• Visiting the blog site at https://chicago.github.io/dev.cityofchicago.org/blog/index.html and click on "Home" in the upper-left hand nav bar. It fails to take you to the homepage at https://chicago.github.io/dev.cityofchicago.org/index.html and simply keeps you on the blog page.
• On the blog page, clicking "Older Entries" will provide a 404.
• Clicking "Read More" fails to take it to the blog post. Right now, blogs are appearing at root/category/year/month/day/title.html instead of the blog/ subdirectory.
• Clicking on blog titles in the footer leads to a 404.
