QtPolylineInput.*
The need to split QtPolylineInput into a templated class and a
non-template base class exists, but there is not need to split the header
into two headers. QtPolylineInput_non_templated_base can be seen as an
auxiliary class of QtPolylineInput.
- Turn Point_2<K> into K::Point_2 in <CGAL/IO/QtConverter.h>, to avoid the
inclusion of <CGAL/Point_2.h>.
- Put most Qt Resource files into the CGALQt4 library, instead of linking
them into the demo.
