flatcam-wsl/FlatCAMEditor.py
Marius Stanciu e6d431c9e3 - removed the raise statement in do_worker_task() function as this is fatal in conjunction with PyQt5 
- 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)
