- updated the translation strings
- updated the Tools Database to include all the Geometry keys in the every tool from database
- made sure that the Operation Type values ('Iso', 'Rough' and 'Finish') are not translated as this may create issues all over the application
- Copper Thieving Tool added a new parameter to select what extra geometry to include in the Pattern Plating Mask; added it to the Preferences

- fixed issue in Corner Markers Tool that crashed the app if only one corner was checked
- fixed issue in Isolation Tool where Area Isolation selection was not working
- made sure that the right tools go only to the intended use, in Tools Database otherwise an error status message is created and Tools DB is closed on adding a wrong tool
- fixed the usage for Tools Database in Unix-like OS's
- done some modest refactoring
- fixed the Search and Add feature in Geometry Object UI
- fixed Paint, Isolation and NCC Tools such the translated comboboxes values are now stored as indexes instead of translated words as before
- in Geometry Object made sure that the widgets in the Tool Table gets populated regardless of encountering non-recognizable translated values
- in Paint Tool found a small bug and fixed it

- in Code Editor, when changing text, the Save Code button will change color (text and icon) to red and after save it will revert the color to the default one
- in Code Editor some methods rework
- added multiple algorithms for path optimization when generating GCode from an Geometry object beside the original Rtree algorithm: TSA, OR-Tools Basic, OR-Tools metaheuristics
- added controls for Geometry object path optimization in Preferences
