Update: Replaced Django-Mako with DjMako because the latter seems
to be more recent and more actively developed.

Changes are essentially replacing all djangomako.shortcuts import
statements with the stock django.shortcuts ones; because the way
DjMako works is it uses (sort of) the built-in Django facilities.

Chanages also applied to the settings file basically reflect the
required and optional stuff for DjMako as seen here:
