Remove warnings from doxywizard

With newer versions of qt5 (e.g. 5.14.0), we get warnings like:
```
...\doxygen\addon\doxywizard\doxywizard.cpp(346): warning C4996: 'QString::sprintf': Use asprintf(), arg() or QTextStream instead
D:\Qt\qt-everywhere-src-5.14.0\install_nmake_2017_32\include\QtCore/qstring.h(382): note: see declaration of 'QString::sprintf'

...\doxygen\addon\doxywizard\wizard.cpp(372): warning C4996: 'QPalette::foreground': Use QPalette::windowText() instead
D:\Qt\qt-everywhere-src-5.14.0\install_nmake_2017_32\include\QtGui/qpalette.h(147): note: see declaration of 'QPalette::foreground'
```
this has been corrected (ran compilation  with qt4 as well).
