Instead of intializing the text fields and then changing the font scale via signal-rigmarole, pass down the font-scale at construction time. Since the fontPrintScale is only set in print mode, we also can access it directly instead of testing for printMode. Since the DiveTextItem is not updated using signals anymore, the connected flag can be removed. The commit is larger than I had hoped for, but this makes things ultimately less brittle.
