Blog skeleton is not a subproject as implied.

In issue #33 I shuffled the content around a bit. Taking a look at it again, I think I was confused. I've updated the page so that the blog skeleton doesn't seem like a sub-project.

- Moved directory information to the blog skeleton section.
- Removed reference to going back to your Sculpin project before
  downloading the blog skeleton. That was bad information.
- Fixed white space issues.
