[Qt] Fixed 64bit

[Den Jean]

Hi,

V1.65: 29 Sep 2008: Fixed 64bit compilation, 
QSysInfo_windowsVersion,QPrinterInfo_supportedPaperSizes

I removed the QetDesktopPalette code in windowsflags (to cleanup the demo),
It is still available upon request.

This release is mainly to fix 64bit compilation (reported by Treeve).
