- added a new parameter in the Tool Film which control the thickness of the stroke width in the resulting SVG. It's a scale parameter.

- whatever was the visibility of the corresponding toolbar when we enter in the Editor, it will be set after exit from the Editor (either Geometry Editor or Excellon Editor).
- added ability to be detached for the tabs in the Notebook section (Project, Selected and Tool)
- added ability for all detachable tabs to be restored to the same position from where they were detached.
- restored the way the tools autoloaded the objects in the comboboxes
