- fixed issue with arrays of items could not be added in the Gerber/Excellon Editor when a translation is used

- fixed issue in the Excellon Editor where the Space key did not toggle the direction of the array of drills
- combed the application strings all over the app and trimmed them up until those starting with letter 'O'
- updated the translation strings
