- reorganized the Edit -> Preferences -> Global
- redesigned the messagebox that is showed when quiting ot creating a New Project: now it has an option ('Cancel') to abort the process returning to the app
- added a try - except clause for the situations when for a font can't be determined the family and name
- moved font parsing to the Geometry Editor: it is done everytime the Text tool is invoked
- made sure that the HPGL postprocessor is not populated in the Excellon postprocessors in Preferences as it make no sense (HPGL is useful only for Geometries)
