Cannot compile under Windows when Windows headers are included after Qt headers

If using this sequence of includes:

#include <QtCore>
#include <windows.h>

then I cannot compile the application anymore. This is caused by the following line in qnetworksession.h:

#undef interface

This basically removes the "interface" keyword, which is used by Microsoft Visual Studio compilers

Workaround: #include all windows headers before any Qt headers
