- fixed an issue due of recent changes that made the application think that is run always for the first time; fixed not applying the selected language translation

- some more code is refactored in the Preferences
- the axis will now be drawn on the canvas as they were left in the previous run (just like the HUD and the Workspace)
- for processors with less than 4 cores now the default number of workers is 1 (changed from 2)
- some graphical settings go now directly to the defaults dictionary and will not pass through the `options` app dictionary
