Use local_settings.py to override parts of settings.py

Rather than parsing settings.local at the top of settings.py
Change local_settings.py so that GeoIP path is absolute instead of relative.

Also made changes to views.py where the GeoIP db was being used.
Merge pull request #9 from dfedorth/local_settings
