resources that are on the internet aren't found on air-gapped networks #87

It would be very nice if there was a local alternative for resources that are normally found on the internet (such as avatars from gravatar, some fonts, etc...). When using codebrag in an air-gapped network, they can't be found so it doesn't look as good as it could. It also takes a lot of time to load pages since these resources can't be found on air-gapped networks, and browser waits until timeout
