[gparted] Make the File System Support dialog resizable (#342682)

commit 6f9b99f13822aa6beedff301d398995271756ce5

    Make the File System Support dialog resizable (#342682)
    
    Make the dialog resizable, add a vertical scrollbar and set the minimum
    (and therefore initial) height to 500 pixels.  This is so that the
    dialog entirely fits on an 800x600 screen, thus allowing the rescan
    button to be pressed.
    
    100 pixel difference is to account for the size of the top and bottom
    GNOME 2 panels and two sets of title bars.  Two sets of title bars
    because the window manager tries to place the top of dialog title bars
    in line with the bottom of the main window title bar.
    
    Bug #342682 - too much information in 'features' dialog
