Kwabena W. Agyeman 6699ea4d0e Added RGB LUT.
And modified the rainbow table so that the RGB888 to RGB565 translation
is done using a rounding technique versus hard floor. This is also used
for the RGB565<->RGB888 LUTs.

Additionally, I added a bunch of stuff to the image library to make
working with images easier. I will using these helpers in the future.

Finally, I cleaned up trailing space in the font stuff (pet peeve).
