Scrolling Text Slows down Rainbow/RainbowCycle

[lancewilhelm]

By having scrolling text it slows down the cycle of the rainbow animations. There is some slowing of the program going on. It needs to be addressed. The scrolling should have no effect on the rainbow animation.

So, optimized the code in scrollingText to try and address this. I rewrote several functions to elimate redundant writing of states or colors or unnecessary ones. This addressed this problem, but still not fully. When the scrolling speed is high, both the scrolling speed and animation take a hit. This will need to be addressed later. Right now it is usable.
