Make console version of the board easier to read

[erik-stephens]

I think the layout is about as good as we'll get for a text based console. However, some use of ANSI color & bold codes should make it considerably easy to read. Some ideas:

• Have the entire board use a common background color, something that will be legible both for white & black foregrounds.
• The pieces should be in bold.
• The white pieces should use a white or off-white foreground while the black pieces use a black or dark gray foreground.
• The jail pieces should use a red foreground.
• The point numbers should use a subdued color.
