- moved the initialization of the FlatCAM editors after a read of the default values. If I don't do this then only at the first start of the application the Editors are not functional as the Editor objects are most likely destroyed

- fixed bug in FlatCAM editors that caused the shapes to be drawn without resolution when the app units where INCH
- modified the transformation functions in all classes in camlib.py and FlatCAMObj.py to work with empty geometries

FlatCAMObj.py
