GFM-Style Fenced Code Blocks Only (no lang attribute)

Removing the additional code that I applied previously to implement the `data-lang` attribute. In retrospect, this was a bad idea; as the existing implementation does a good job with this already when used properly.

Many thanks to Michel Fortin for his help in accomplishing these changes :-) I hope this might be merged into the official copy at some point in the future.
