Replace pystache with chevron (kerrickstaley#93)

pystache has been unmaintained for a long time, with the [last commit] to [defunkt/pystache] being from September 2014. By now it is not installable with up-to-date setuptools. Luckily, genanki uses only the most basic of mustache API, and [chevron] fills the gap nicely. Tests are passing for me again.
