unknow-icon.gif missing with Django 1.9

[bdesbiolles]

Hi,

with Django 1.9, some static images have changed like unknow-icon.gif which is know unknow-icon.svg. This causes graphical glitches (missing icon).

This image is used by super_inlines/templates/admin/edit_inline/tabular.html at line 19.

From where I stand I see two quick solutions:

• change icon-unknown.gif to icon-unknown.svg and bump the version number (breaking compatibility).
• add the image within the project static files to keep compatibility.

I can contribute to the project, I just wanted an opinion before submitting a PR directly.

Thanks,

Baptiste

IMHO, it's best to update the reference and push the version. Copying files from django in order to support older, unsupported (by upstream) versions is too dirty.
