- fixed the HPGL code geometry rendering when travel

- fixed the message box layout when asking to save the current work
- made sure that whenever the HPGL postprocessor is selected the Toolchange is always ON and the MultiDepth is OFF
- the HPGL postprocessor entry is not allowed in Excellon Object postprocessor selection combobox as it is only applicable for Geometry
