Creates a wimp colour setting menu
* R1 ® menu title string
R2 ® menu handler
* R0 = handle of the menu
R1 — Preserved
Use: This call creates standard WIMP colour setting menu. R1 on entry points to the title string for the menu. If R2 ¹ 0 then it points to the handler common for all 16 items. (See also "MenuUtil_Add" for more info about item handlers). Despite the fact that the same handler is invoked with all items it is still possible to distinguish user selection. MenuUtil_Decode returns not only pointer to the handler but also the number (position) of selected item in the menu. Actually this number is equal to the colour number.
