Radomir Dopieralski f5685ebe46 Specify POLICY_CHECK_FUNCTION as a string
We don't want code in our settings.py and local_settings.py, and in
particular we don't want to have to import Python objects from all over
to set them as setting values -- instead, we can specify those as import
path strings. This also solves problems with importing order and loops.

This change is backwards-compatible, in the sense that you can still
import the objects directly and set them as the setting values.
