Added the ability to toggle what events are tracked to allow the user to disable, touch, scrolling or pointer events.
Merge branch 'eventOptions' of git://github.com/AdaRoseEdwards/ftscroller into AdaRoseEdwards-eventOptions
Update the ability to toggle input methods:
 - Rename the instance option from disabledEvents to disabledInputMethods for clarity
 - Remove the pointer definition and focus on methods, leaving mouse, touch and scroll
 - Fix pointer and touch options for a scroller disabling them for all scrollers
 - Handle pen input types as mouse for the purpose of disabling
 - Update readme
