Create installer with qmake

This is seriously flawed. makensis is run twice for some reason. I also
noticed that the data and xslt directories under packaging/windows aren't
created when running make install. Running
	make -f Makefile.Release install_marbledir install_deploy
works, but obviously this should be taken care of by the dependency.

The installed binary under Windows is not finding its icon, the
translations are missing... lots of work left to do here.
