Added support for HTML (.html,.htm) uses existing twig parser, updated read.me to reflect enhancement.

Whoops I didn't add tests. Doing that now (hopefully correctly, pretty nooby on writing test assertions).

Sorry I have no clue what the third parameter of the verifyComment function is supposed to be about so I don't know what to set it to (assuming it's what the error is about)

Can you fix this or tell me how. (see travisCL error)

  AssertionError: expected 1 to be 4

  + expected - actual

  -1

  +4

third parameter is the line number of the comment, thanks for the PR btw

Well, with that tip and getting mocha running locally. It's ready now.
So sorry about all the commits. You can squash at your end?

Been self-learning node.js via a workflow project and also doing PRs is a good way to learn I think.
With this PR for your repo I learned a bit about mocha and can use your repo as a nice example to start including tests in mine so time well spent. So no, thank you.

Thanks, will hopefully get to merge it soon when I'll have more time
