- optimized the toggle of annotations; now there is no need to replot the entire CNCJob object too on toggling of the annotations

- on toggling off the plot visibility the annotations are turned off too
- updated translations; Russian translation at 76% (using Yandex translator engine - needs verification by a native speaker of Russian)
- RELEASE 8.919
