Django 1.5 compatibility

A couple of tweaks to make this compatible with Django 1.5.

 + Removes `verify_exists`, which was deprecated in Django 1.3.1
 + No longer uses built-in `localflavor`, uses packaged version
remove deprecated verify_exists argument from URLField constructor calls
add eclipse's files to git ignore list
use (possible customized) settings.AUTH_USER_MODEL instead of auth.User
and organizing imports (remove duplicated settings import)
