All: fix spurious wheel scroll events caused when using modern mice. 

Modern mice feature horizontal scrolling capabilities and those end
up being treated by KiCad as regular scroll events causing confusion
among users.

The fix works by discarding the handling of wheel events other than
the ones for the vertical axis.
