Fix incorrect mouse wheel/touchpad scrolling scale (LP: #1607240)
and also add sufficient precision that high-resolution touchpad
scrolling now works! (LP: #1607223)
This fixes two mistakes:
1. angleDelta is not in degrees but eighths of a degree, so the magic
constant 15 should be 120 (QWheelEvent::DefaultDeltasPerStep)
[http://doc.qt.io/qt-5/qwheelevent.html#angleDelta].
2. When converting from Qt back into a Mir event we forgot completely
to divide by the same factor to get back to the Mir scale of things. (LP: #1607223, #1607240)
