Quickie on issue https://github.com/Mischback/django-oweb/issues/17

Yeah, I know this branch is called issue15, but issue https://github.com/Mischback/django-oweb/issues/15 was fixed real quick and the solution applies to issue https://github.com/Mischback/django-oweb/issues/17 aswell.

So, here we are. Throw rocks if you never implemented two features in one branch. *narf*
