Split Markdown rendering & reference gathering

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.

# example:

# class IssueParser < BaseParser

# `references_relation` or overwrite `referenced_by`. The
# `references_relation` method is supposed to return an
# ActiveRecord::Relation used as a base relation for retrieving the objects
# referenced in a set of HTML nodes.
#
# Each class can implement two additional methods:
#
# * `nodes_user_can_reference`: returns an Array of nodes the given user can
# refer to.
# * `nodes_visible_to_user`: returns an Array of nodes that are visible to
# the given user.
#
# You only need to overwrite these methods if you want to tweak who can see
# which references. For example, the IssueParser class defines its own
