MouseWheel behavior in TrackBase and Spinner
http://bugs.adobe.com/jira/browse/SDK-20154 - awkward mouse wheel behavior on Gumbo Sliders
When Slider is in focus, it listens for the mouseWheel event on the systemManager in the capture phase. Added the same support to Spinner (and thus NumericStepper). I decided against moving the functionality into Range because range is an abstract class that has no user interaction code in it. Thus it didn?\226?\128?\153t seem correct to put mouse handling code into it.
I updated some of the Halo classes to use the preventDefault/isDefaultPrevented functions instead of using stopPropagation in their mouseWheel handlers.
QE notes: Add test cases for Spinner and NumericStepper
Doc notes: Mention mouse wheel support in Spinner and NumericStepper
Tests run: Spinner, NumericStepper, Slider
Is noteworthy for integration: No
