Multiple Pebbles and ambience/silent changes

[rubdos]

I recently got my hands on a Pebble Time Steel, it's a lovely watch! However, now Rockpool is managing two watches, because I still use my Pebble Time too.

I use the Ambience change triggers on connect/disconnect to get my phone from making noise to complete silent, because I receive my notifications on my watch. Now, I don't take both watches with me, which means that one of my watches disconnects during the day, and my phone goes out of silent mode.

I think it would be beneficial to add some logic to change the ambience on all-disconnected and any-connected events, in my use case.
