Scoreboard colors

[wyattisimo]

I noticed a bug. The wrap method was being sent :success, :pending, and :failure keys. Since those keys don't exist in the VT100_CODES hash, all the scoreboard values were displaying in the default white.

I also simplified the logic for fetching color codes because I noticed the following two issues:

1. The recursive call console_code_for(:white) will result in infinite recursion if the :white key doesn't exist in the VT100_CODES hash.
2. The console_code_for method had logic to allow the caller to send the actual color code instead of a symbol. However, I cannot find any place where a color code is sent to that method, so the added complexity of that logic seemed unnecessary.
