Implement text abbreviation

When rendering text, gfx_puttext can now abbreviate it with …
to fit within the specified width. Use on window captions.
Now Barber Pole can have a proper caption.

Note that now the caption is centered on the space between the left
edge and the buttons, instead on the entire title bar, so it
may look a little lopsided. It will look better once we put
something to the left side of the title bar.
