Alternate publishing using rake for yaml front matter

With the changes here, I can publish per the instructions here:

http://www.railsonmaui.com/blog/2013/04/27/octopress-setup-with-github-and-org-mode/index.html

Basically, this change just allows turning off the inclusion of the yaml front matter, as that will be included per my rake technique.

There are some changes related to the configuration publishing. I'll be updating this article shortly.

This is how I setup the publishing. The key thing is turning off toc generation.

Note, these settings are with org-mode version
Org-mode version 8.2.3c

The rakefile part is the same as mentioned in the above article.
