- replaced the standard buttons in the QMessageBox's used in the app with custom ones that can have text translated
- updated the POT translation file and the MO/PO files for English and Romanian language
- fixed bug in applying default language on first start
- on activating 'V' key shortcut (zoom fit) the mouse cursor is now jumping to origin (0, 0)
- fixed bug in saving toolbars state; the file was saved before setting the self.defaults['global_toolbar_view]
- finished support for internationalization by adding a set of .po/.mo files for the English language. Unfortunately the final action can be done only when Beta will be out of Beta (no more changes) or when I will decide to stop working on this app.
- changed the tooltip for 'feedrate_rapids' parameter to point out that this parameter is useful only for the Marlin postprocessor
- more work on the translation engine; the app now restarts after a language is applied
- added protection against using Travel Z parameter with negative or zero value (in Geometry).
