Do you believe in magic?

Added a magic foreground color, Color(255,255,255)+1, which triggers a
rotating colorwheel as the fgc draw color rather than a solid color.
Might create others for palettes to clean up some of the palette code.,

Also added meander, capped conway to a specific limit, checked conway
for still life, and added emoticons to conway based on survival or total
party kill.
