Add logic for plucking hyperlinks from cooked html (#1403)
This commit adds a `parseLinks` method to a new module,
`plugins/discourse/references`. `parseLinks` allows us to extract the
hyperlinks from `<a>` tags in "cooked" html.

I added `htmlparser2` as a dependency to parse the html. There were a
lot of options to choose from; I chose htmlparser2 because it has a lot
of usage, reasonable performance, and suits our needs. We use this
dependency in a lightweight and local way, so we can always change it
later if needed.

One thing which was a bit odd: I wasn't able to import it using
`import`, and needed a `require` statement instead.

Test plan: Unit tests added; `yarn test` passes.

This is progress towards [Discourse reference and mention detection][1].
