Staticfiles support

Hi guys,

I implemented the django.contrib.staticfiles app support that was added in 1.3 (https://docs.djangoproject.com/en/1.4/ref/contrib/staticfiles/).

The files are being collected from the media folder and currently installed apps (including django admin) and are copied to the `STATIC_ROOT`, which is the place from where the web server serves these files. Of course, you'll have to edit that setting in your production settings as well as run `python manage.py` during deployment.

If you have any comments or proposed changes, let me know.
