FS#11686 - Kinetic list scrolling for touchscreen

This adds kinetic scrolling to to lists on touchscreen targets and RaaA, like all other OSes on touchscreens have.
It's only enabled in the absolute point mode, so for non-touchscreen and in grid mode nothing changes.

Kinetic scrolling means that the list keeps scrolling (but is decelerating) after you leave the touchscreen with the finger.
Redraw interval and deceleration is hardcoded for now but could be made configurable if desired.
