UTC-based astimezone filter

A version of http://djangosnippets.org/snippets/2388/ which assumes UTC-based dates. This is when you store dates in UTC (as you should), and want to display them in your site's local timezone, and you notice that Django's timesince/time template tags still do not support timezones.

Remove old fields on dumpdata generated json

A small script that takes a manage.py dumpdata generated json file, and removes fields of the specified models. I needed this because i kept my initial data on a json file and after I removed a field on one of my models, the script wouldn't work anymore.

Persistent Session Debugging with Django Debug Toolbar

When using [django debug toolbar](https://github.com/django-debug-toolbar/django-debug-toolbar), I like to be able to turn debugging on and off without having to edit my settings file. This callback makes that possible. Add `?debug=on` to the URL to turn debugging on. It will remain on in the current session until you turn it off with `?debug=off`. Make sure your session middleware comes before your debug toolbar middleware.

SelectRelatedManager

Because select_related() only works on ForeignKeys that are not null or blank, when you are customizing the admin, even if you set "list_select_related=True" you can still end up with way too many querys in the Admin changelist. By adding this code to your model you can decrease the queries dramatically. I found I needed this when I was working with Django apps with a lot of legacy data and I couldn't set the ForeignKey null=False.

Serve admin-media from urls.py

By default the `runserver` command does some magic to automatically serve admin media. This magic doesn't happen when using other servers like gunicorn… But this makes that magic unnecessary by using urls.py to route requests for admin media to the standard static media server. `#include <production_disclaimer.h>`
