QWindowsVistaStyle: Use lighter color for disabled GroupBox label

Browse Source 
The default windows theme does return the same color for enabled and
disabled groupboxes. This patch changes the color to
pal.color(QPalette::Disabled, QPalette::ButtonText) in case
GetThemeColor returns the same color for GBS_NORMAL and GBS_DISABLED
