Merge lp:~maxiberta/django-openid-auth/fix-logo-view into lp:django-openid-auth

[Maximiliano Bertacchini]

Fix logo view to support Django>=1.7.

This should not affect backward compatibility, as the `content_type` argument to the HttpResponse constructor was added in Django==1.0 [0] as an alias to `mimetype`, which was deprecated in Django==1.5, and removed in Django==1.7 [1].

Hahaha, talk about old code.

Thanks for going broken-window-fixing on this tiny but annoying bug!
