Integrated the Nuvola dll, as done previously for IMT. In the process, found a couple of other libraries common to IMT which were still linked to the original icons.pas file, so I fixed those and rebuilt the IMT (just making the executable smaller).

Also figured out a workaround for the issue of restricted characters in replace sequences reported by Paolo Cutini (they could be saved, but then the file could not be reloaded). I'm now escaping those characters to maintain valid XML 1.0.

Built an installer, did the release, updated the Website and source code archive, etc. etc.
