Add support for Android Wear

[rock3r]

Investigate implementing a card for on Android Wear devices, maybe with some custom action (Refresh, most likely). It's probably going to be interesting to have a custom watchface once the public API for that is rolled out. Which will never happen soon enough.

I'd go for a card.

DAT. But also, a watchface at some point.
