Fix FreeCAD/FreeCAD-translations#124 (#25)

This solve such things

1.  If you create new document, it show "Unnamed" name without translations. Solved.
2.  If you open .step file create new document with "Unnamed" name without translations. Solved.
3.  If you open .iges file create new document with "Unnamed" name without translations. Solved.
4.  Add similar translation ability to AppFemPy, AppMeshPy and AppPartPy.
