Merge branch 'release/2.2.0.1' into develop
Update one test now that the error message has changed.
Catch if a template is None.
Remove direct dependence on unittest so we can get test-generators working again.  Relates to #88.
Turn the css/js escaping tests into generators per engine too.
Kajiki expects unicode these days.
Mark this test really as skipping.
Skip tests on weird kajiki behavior....
Drop python-3.2 support since our deps dont support it.
Kill kajiki.
