[PATCH] Correct md2html's output order

[dlcampbell]

Corrects md2html's output order by setting two Python-centric
environment variables before calling it. This ensures two things:

* The io streams are UTF-8, which Python 3 handles natively
* Unbuffered output will create the expected behavior by flushing on
  print() instead of embedding the expected HTML in the <style>
  element due to Python's automatic buffering.
