The eventual goal is to have a test script that behaves well with tox.
Using a stand-alone test script that we control instead of an
out-of-the-box command-line script like nosetests or Distribute's test
should give us more flexibility in dealing with any idiosyncracies
that occur with tox.

Conflicts:
	pystache/init.py
	setup.py

Still need to address Python 3 packaging issues (setup.py, etc).
