Use ugettext instead of ugettext_lazy
Reports from Matthew Wilkes indicate that the regular form of
ugettext works just fine. The downside of ugettext_lazy is that it
prevents pages containing ugettext_lazy-ed text cannot be memcached,
since they cannot be pickled.

Coverage: code coverage testing for Python
Coverage.py is a Python module that measures code coverage during test execution.
It uses the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
