Combined separate horizontal/vertical mouse wheel event types

Browse Source 
Instead of separate Event::MouseWheel{Vertical,Horizontal}Moved events, a single Event::MouseWheelScrolled event is used for all wheel-related events.
The new Mouse::Wheel enum is used to differentiate between mouse wheels.
