Implement WB exclude feature

Implement WB exclude feature

UCI2WB collects moves sent by the engne in analysis mode from the currmove,
currmovenumber info commands. After the full set for the current position
has been completed, UCI2Wb becomes sensitive for WB include and exclude
commands, to switch the moves in the list on or off. If not all moves
are on, the 'go infinite' will be accompanied by 'searchmoves'. If all
moves are off, the current search is allowed to continue.
