while some scrolling issues where fixed since 6.0.1, some where introduced,
namely:
* for firefox, the correct event to listen to is 'wheel' not 'mousewheel'
* the spinner scroll direction was incorrect
* the boxOverflow scroll direction was incorrect
* the boxOverflow scroll amount was too high
functions were copied from extjs source, eslintified, and adapted
