* Removes all translate call on the parameter name and moves them into the title instead allowing to decouple visualization from code logic * Removes all translate calls from the Exporter class property Name and moves the translation logic when setting the QListWidgetItems for the formatList * Adds missing call to translation function for the export action on GraphicsScene
