- [bug] Changed setup.py to skip installing markupsafe
if Python version is < 2.6 or is between 3.0 and
less than 3.3, as Markupsafe now only supports 2.6->2.X,
3.3->3.X.
- [bug] Fixed regression where "entity" filter wasn't
converted for py3k properly (added tests.)
- [bug] Fixed bug where mako-render script wasn't
compatible with Py3k.
- [bug] Cleaned up all the various deprecation/
file warnings when running the tests under
various Pythons with warnings turned on.
