richedit: Use 32-bit rather than 16-bit trackbar value for scrolling.

[Dylan Smith]

The WM_VSCROLL message stores a 16-bit trackbar position value in the
wParam for a SB_THUMBTRACK or SB_THUMBPOSITION scroll request, however a
32-bit value for the trackbar position can be obtained using
GetScrollInfo to avoid truncating this value when working with a large
amount of text.
