Expose an 'active' property for disabling Pusher entirely.

Instead of only exposing imperative functions for controlling the state
of the socket, let's expose a property to make binding to it easier.
Also when the socket switches to inactive, we should explicitly stop the
timers to avoid wasting cycles and potentially waking up the app.
