Title: Use the just released hastache-0.5

I [patched](http://hdiff.luite.com/cgit/hastache/commit/?id=a9f4f50be13ec7b2fee741bdbec711f26fc77408) hastache to have (among other things) an effectful MuContex which allows users to throw exceptions for undefined variables.

This patch adapts criterion to these new types.
