Updated JS redirect from .github.com to .github.io

Since Github will be redirecting ___.github.com URLs to ___.github.io, I don't think anyone could load `addyosmani.github.com` and have our JS execute without having already been redirected to `addyosmani.github.io`. I switched the version as well, and created a tag for `v0.1.4`, though I don't know if this PR will include my tag.
