-better support for Qt4 as frameworks

before this patch -F<framework> dir had to be added manually in some way
when using Qt4 installed as framework and when using FindQt4.cmake directly,
i.e. without UseQt4.cmake. With this patch the framework dir is
automatically added to QT_INCLUDE_DIR when Qt is installed as a framework.

Ok by Clinton, tested already in KDE by Mike Arthur.
