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. I originally wanted to colour the large text like this, then due to lack of free memory and experience I coloured the monkey, now both are coloured. As usual, it should work on all supported computers.

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