wayland: add support for precise scrolling

Browse Source 
The default value for a standard mouse is 10.0. Because we don't want to
multiply the value in the input config file we scale it down to 1.0.

Hopefully this should work for more precise mousewheels or touchpad, but
I don't have access to such hardware.
