[Bug-gnubg] Marks for doubtful/ bad move not updated after rollout

[Misja Alma]

Hi,

I have an analyzed match where I have rolled out all the doubtful/ bad
moves afterwards.
Sometimes this proved gnubg's analysis to be incorrect because the
played move was correct after all.
This is correctly shown in the analysis panel, however in the moves
explorer all the original marks have been left as they were.
It would be nicer if the marks had been adjusted according to the
rollout results.

Cheers,
Misja
