Viewport is moved to top left corner after save

[Atria1234]

It is done because the layout needs to be normalized before it is saved.
Either:

• move viewport back to original position after the save is done
• make a copy of the layout, then normalize and save the copy

Since some players might have used the fact that viewport was reset as a hint that save is done, add star to window title as long as there are unsaved changes.
