Optionally label the colours in Guess with letters of the alphabet.

Browse Source 
Labels are toggled on and off by pressing L (just like Map). Might
help colour-blind users, and might also make it easier to describe
game positions to other people because `abbc' has fewer syllables
than `red, yellow, yellow, green', and hugely fewer letters if
you're typing it.
