Pass through IP addresses

[mrmowgli]

If you look at the original fauxmo project you will see there is a multiple alexa solution that differentiates on IP address. I'd love it if you pass through the IP address (Or better yet the mac address) of each device so I can run scripts against the specific echo that picked it up.

Thanks!

Hi @mrmowgli I'd love to merge in a PR on this topic. I have not had a lot of time to devote to my IoT work lately.
