Use local images in test/help_dialog(.html)

- create subdir test/images
- copy images used by test/help_dialog to this subdir
- fix image URL's in test/help_dialog.html accordingly

CMake: copy the entire test/images folder to the <build>/data folder

This enables the demo test/help_dialog.cxx to find its images.
