+- fixed issue after Geometry object edit; the GCode made from an edited object did not reflect the changes in the object
 - in Object UI, the Scale FCDoubleSpinner will no longer work for Return key press due of issues of unwanted scaling on focusOut event
 - in FlatCAMGeometry fixed the scale and offset methods to always process the self.solid_geometry
 - Calibration Tool - finished the calibrated object creation method
 - updated the POT file
 - fixed an error in the German PO file
 - updated the languages PO files
+- some fixes on the app.jump_to() method
+- made sure that the ToolFilm will not start saving a file if there are no objects loaded
