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.

+ //          -c    add the "const" keyword to definition
+ //          -z    terminate the array with a zero (useful for embedded C strings)
