    A list item, which can display information about files.
    
    The FileListItem class is a TextListItem, which contains additional
    information about a file such as its type and a suitable icon
    surface.

    The 'filetype' argument of the constructor must be an integer value,
    which matches a valid value of the stat.S_IF* data values. It will
    be stored in the 'filetype' attribute of the FileSystem object.
    Take a look at the stat module and os.stat() documentation for more
    details about the different values.

    item = FileSystem ('myfile', stat.S_IFDIR)

    The passed filename will be stored in the 'text' attribute of the
    FileListItem as described in the TextListItem documentation.

    Dependant on the 'filetype' value a specific icon surface will be
    set in the 'icon' attribute of the list item. 

    Attributes:
    icon     - The icon to display on the FileListItem.
    filetype - The type of the file.
