Incompatibility with django-admin-sortable2

[maksjood]

Hi. Thanks for the package; but another very usefull package is admin-sortable2. Unfortunately, mixing admin-sortable classes into SubAdmin class of yours, leads to errors, as this error:

NoReverseMatch at /secret-admin/content/album/416/track/ Reverse for 'content_track_sortable_update' with no arguments not found. 1 pattern(s) tried: ['secret\\-admin\\/content\\/album\\/(.+)/track/adminsortable2_update/$']
