------------------
- BACKWARDS-INCOMPATIBLE: Renamed template tag library from ``form_utils_tags``
to ``form_utils``.
- BACKWARDS-INCOMPATIBLE: Removed ``FORM_UTILS_MEDIA_URL`` setting and updated
to use ``STATIC_URL`` rather than ``MEDIA_URL`` throughout.
- Added "error" class to row_attrs for fields with errors. Thanks Aron
Griffis.
- Dropped explicit support for Django versions prior to 1.4 and Python
versions prior to 2.6.
