'networkInterface' event

[richardschneider]

I'm doing a peer-2-peer app and want to discover other peers when a new network interface is discovered. This PR emits a 'networkInterface' event.

Also, I found some weirdness on Windows when the laptop sleeps and then wakes up. So a couple of socket calls are wrapped in a try/catch.

@mafintosh Again, thanks for this library!

@mafintosh any comment?

[daviddias]

@richardschneider can you add tests for these changes?

[mafintosh]

@richardschneider sorry for the delay. this looks good to me. are the try catches and membership drops necessary?

I was just trying do a PR for try/catch on socket.setMulticastInterface. This will be something I want as well.
@mafintosh are we going to merge this or another PR is preferred?

[mafintosh]

@drahnieR are you seeing errors without the try/catch ?

[drahnieR]

@mafintosh yes, this is what i got. I'm using https://github.com/watson/bonjour btw

Hey @mafintosh, can you merge this. I think the try-catch will help.

[DiegoRBaquero]

@mafintosh can we get maintainer access for this package as well, similarly to chromecasts?

[mafintosh]

Thanks for the patience (and ping @alxhotel). Releasing now
