    properties-window: Truncate name in window title
    
    We display the a file's basename in the properties window title.
    
        exmaple.txt Properties
    
    If a file has a really long name, this makes the dialog way too wide.

Properties
    
    Yes, that went past the 72 characters limit for a commit message lines,
    which proves the point.
    
    Instead, let's truncate the basename to a reasonable limit.
    The full name is available in the Basic tab of properties dialog anyway.
