[Bug-gnubg] BUG: Tutor mode

[Ian Shaw]

I have found a couple of problems in tutor mode.

1. The final (Double by me / Pass by the bot) of a game is not analysed
and stored in the analysis window.

2. If the tutor flags a play at 0-ply, and I use the hint window to get
a 2-ply analysis that overturns the error, there are two problems,
probably related.
        a. Once I've clicked OK and play the move again it flags an
error again.
        b. The two ply analysis is not stored in the analysis window.

3. Not so much a bug as a question of philosophy. If I "think again" and
make the correct move, there is no error recorded in the stats. It would
be good to have the option of recording the original error yet proceed
with the correct move. I suspect this is almost impossible until someone
implements the recording of "variation branches" in the move records, so
I'll not hold my breath.
