Add city & country data to the log

[Krisnadi]

Can I make an enhancement to this package by adding more information to the request log such as city & country by the requester IP address?
I'm going to integrate it with GeoIP.

@Krisnadi this looks like a good idea. From the django docs it does say that GeoIP is deprecated in favor of GeoIP2. Have you started on this or is there a PR?
