- added a traceback report in the TCL Shell for the errors that don't allow creation of an object; useful to trace exceptions/errors

- in case that the Toolchange X,Y parameter in Selected (or in Preferences) are deleted then the app will still do the job using the current coordinates for toolchange
- fixed an issue in camlib.CNCJob where tha variable self.toolchange_xy was used for 2 different purposes which created loss of information.
