Fix #2861, provide consistent mouse-wheel zoom direction, plus a GUI preference to invert (#3749)

Browse Source 
* Make mouse-wheel in 2D toolpath zoom in the same direction as it does in 3D and 3D-preview

* Add a GUI preference setting for whether to invert the direction that
mouse-wheel scrolling will zoom in the 2D and 3D panels.
