Once the new icons were in place, I had to re-do all screenshots for the tutorial, help and example documents. Then I worked through the tutorial and help files, and updated them, adding information about the new features and the new schema. In the process, I removed the SVG schema from the schemas folder -- it's not needed for validation, because all its definitions are built into the main schema by ROMA. That simplifies things considerably. I also updated documentation to include more detail about the Nuvola icons.
