No real changes, just a tiny refactoring in wxMSW wxListCtrl.

Reuse wxListCtrl::SetTextColour() instead of calling ListView_SetTextColor()
from wxListCtrl::SetForegroundColour().

This ensures that the two functions behave consistently, e.g. they now both
use palette-relative colour instead of a raw RGB value in the case of the
latter method as before. This probably doesn't change anything in practice
nowadays.
