Fix #533: staticfiles setup for Django 1.4
Set up Apache to serve static files

Modify the dev server setup script to add a line to the Apache
configuration to serve static files at /static/.

Also, replace the old /media/ and /static/ URLconfs with Django's
shortcut functions that do the same thing but only in debug mode
(letting Apache serve those URLs in production mode).
Remove instructions that reference the old admin media location
Fix import for staticfiles_urlpatterns
