- fixed bug in FlatCAMObj.FlatCAMGeometry.ui_disconnect(); the widgets signals were not disconnected from handlers when required therefore the signals were connected in an exponential way

- some changes in the widgets used in the Selected tab for Geometry object
- some PEP8 cleanup in FlatCAMObj.py

flatcamEditors/FlatCAMGrbEditor.py
