Updated IP-Addresses

See https://api.github.com/meta for current list of ips!
More info here: http://developer.github.com/v3/meta/

Maybe fetch the list on app-start?

I'm starting to wonder if this is a necessary feature at all, since someone could just spoof the IP address since the return value isn't at all necessary. Thoughts?

I'm also about done with issue#2 which would solve this issue in its entirety.

I was just going too suggest #2, maybe its a better solution yes
