Don't score as an immediate draw 2-fold repetitions of the root position In the current version a search stops when the current position is the same as any position earlier in the search stack, including the root position but excluding positions before the root. The new version makes an exception for repeating the root position. This gives correct scores for moves in the MultiPV > 1 mode. Fixes #948 (see it for the detailed description of the bug).
