First commit with new files for extending the vigraqt with qgraphicsview-framework. Also fixed the creation of QImages in createqimage.hxx to work with Qt >=4. The old function used deprecated Qt3 syntax.
Added components for the graphicsview framework of Qt 4.X. These classes allow to display BasicImages on a GraphicsScene. Additionally an appropriate view was implemented as well as a special graphicsitemtype, which is returned when adding a BasicImage to a vigraqgraphcisscene
Added the new graphicsview-framework files to the CMake build scripts.
Finalized vigraqimage example using the qgraphicsview framework, which comes with Qt 4.X. An image can be displayed, browsed, normalized, analyzed, and printed to printer or to pdf file.
added finding of PYTHON_SITE_PACKAGES directory to the file for installation path
Edited PythonSIP QtProject file: although not working - a reference to the libvigraqt would be required for the vigraqt-python bindings to be linked with qmake/make
restored default unix-system path inside the QMake include file to /usr/local
