Allow dragging of coloured pegs from previous guesses. Also
reorganise the colours so there are fewer of those terribly
computery cyan and magenta shades, and more good old-fashioned
colours with simple names like orange and purple. Finally, change
the `right place' marking peg colour from red to black, in line with
at least _my_ old Mastermind set (I faintly suspect red marker pegs
of being an Americanism) and also so that the marker pegs and the
coloured pegs have no colours in common.
