Update index blog file

We have updated the index blog file to index.blog.json to not mess up with other files. If this one is being used, no problem! You can set the desired file name in the constructor as well:

var blog = new GithubBlog("your_blog/repo", "your_index_file.json");

Removing dependency from GitCDN

v0.0.2

Loading files directly from Github

First release

This should contain the basics to get this project started.
