Merge pull request nix-community#330 from nix-community/joerg-ci

bump version to 1.3.0

Detect IPv6 automatically, Rewrite kexec url

This uses ip r g 1.1.1.1 to test if there's any route to an IPv4
internet host

If that fails and the url is a github.com one it will change github.com
to gh-v6.com,
as specified in the documentation

This saves the user from an extra manual step and makes nixos-anywhere
better
