Missing import in `d1_gmn.settings_template`

[iannesbitt]

The gmn 3.5.2 settings template currently calls d1_common.util.nested_update without importing the module first. The solution is to add the module import (import d1_common.util) to the top of the template and to any affected settings.py file.
