Show debug info for django.contrib.staticfiles

[btubbs]

Probably my most frequently used django-debug-toolbar feature is the Templates pane, to help me know exactly where a rendered template is coming from. With the addition of django.contrib.staticfiles (formerly django-staticfiles) to Django, it would be very nice to have a new Static Files pane, similar to the Templates pane, to tell me exactly where to find the static files that are being served.

Woo, great idea! Feel free to have a look at how the findstatic management command figures out the places of specific files.
