Correctly coloured large text

The large blue "DONKEY KONG" text in the introduction has colours closer to the original arcade version. Finally, this screen looks like I imagined it a year ago. At that time, I originally wanted to colour the large text like this, then due to lack of free memory and experience I coloured only the monkey, now both are coloured. Both use a raster multicolour effect, which I timed according to the computer type the game is running on, but as usual, it should work on all supported computers.

I have not yet fixed the remaining flaws in the jumping part of the opening monkey animation that appeared after moving the animation after each game start. Hopefully in the next version.
