Disable Google fonts download for offline use

[jpsnyder]

While trying out luigi in an offline environment, I noticed the interface takes a verrry long time to load.
This is because it is trying to access fonts.googleapis.com.

Eventually it loads after it fails to connect. However, is there a way to configure the luigi interface to tell it we are offline?

I noticed I get the following 404 errors. I assume they are trying to phone home?
