Title: Add haml template for environment block (block_environment.html.haml in haml/html5)

Add this block to accommodate blocks like

```
[env.theorem]
--
There are infinitely many primes.
--
``

This is to facilitate the cooperation of the html and latex backends, so that both can properly render the same
source text. See the pull request for the EnvironmentBlock for more details.
