1.6.
Django commit https://github.com/django/django/commit/3647c0a49a2f4535b8a9aba40e662743e4d53e76 broke taggit. This commit fixes that. Thanks akaariai for the patch (see https://code.djangoproject.com/ticket/19399 for details).
Fixed various ForeignObject compatibility issues

Unfortunately it was not possible to use ForeignObject directly
due to Django 1.5 compatibility requirement.
Merge remote-tracking branch 'akaariai/path_info_fix' into develop
Restored 1.5 compat.
