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?

404 GET /static/visualiser/lib/jquery-1.10.0.min.map (127.0.0.1)  0.83ms
404 GET /static/visualiser/lib/d3/dagre-d3.min.map (127.0.0.1)  0.86ms
404 GET /static/visualiser/lib/bootstrap-toggle/js/bootstrap-toggle.min.js.map (127.0.0.1)  0.89ms

I tracked this down to the AdminLTE library. It imports the google fonts in AdminLTE.min.css
ColorlibHQ/AdminLTE#1421

I just went ahead and blocked fonts.googleapi.com on my system, which fixes the slow down for me.
