[pango/segmentation-tweaks] pango-segmentation: Add a --text option

[Matthias Clasen <matthiasc src gnome org>]

    pango-segmentation: Add a --text option
    
    Change pango-segmentation to interpret its argument as
    a filename, and add a --text=STRING option to specify
    the text directly. This matches what pango-view does.
