overview: Expose scroll-events

Browse Source 
Using the scroll wheel in the window picker should switch workspaces.
As the picker doesn't have a visible boundary though, it makes sense
to accept scroll-event for the entire overview area. Rather than
making the overview's main actor public, expose scroll-events via
a signal.
