Notifications?

[zuzak]

We could do something cool with now playing notifications. Thoughts?

Server needs a moment to read meta-data, so it should be delayed until that is ready, perhaps waiting up to a second before displaying a notification? If it's handled by the now playing callback then it's trivially handled in that callback.

Should all open clients be notified? I guess it's simple enough to start working on an options page where things like langselect and display notifications could be put.

Browsers need to request permission, so perhaps that's enough of a config?
