This splits the Markdown rendering and reference extraction phases into two distinct code bases. The reference extraction phase no longer relies on the html-pipeline Gem (and any related code) and allows for extracting of references from multiple HTML nodes in a single pass. This means that if you want to extract user references from 200 comments you no longer need to run 200 times N number of queries, instead only a handful of queries may be needed.
