Title: Reading and writing condition-files to OGS projects

This PR extends OGS-project-files (gsp) to also include conditon files (cnd).
I also changed to way ProjectData is given to any Qt-XML-Interface from a pointer to a reference (I don't remember why there was a pointer, it's not necessary).

This functionality is (again) something needed for the workflow description in the upcoming Computational Hydrology tutorial.
