    File browser: combobox with all parent dirs
    
    For the indentation we use simply a text cell renderer with spaces (two
    spaces for one level).

-- File browser
-       - list with all parent directories
-
 - Some various improvements:
        - Make a copy of a file before saving it for the first time (with a name like "file~")
        - Autosave files every X minutes
