Subject: rbutil: Add nice Buttons (FS 7294, heavily modified). Buttons are
 from the gnome-icon-theme (GPL) and are in png format. In rbutil/icons there
 is bin2c.c which can convert those pngs to *.c and *.h. Call it with bin2c
 *.png (shell expansion). The Makefile (Linux/ Mac) needs updates to use this.
