#183 Fix heuristically incorrect behaviour observed in English Draughts
Update version name
Fixes to heuristic mechanism in som transposition cases
Addressed some scaling issues with the piece heuristic (with piece counts/values)
Fixed bug that could result in incorrect state calculation in at least iterated games
Modified the way that plans are used to remove the need to search, so as to make test suites operate more 'realistically' (with pre-warmed serach trees on the move they are being asked about)
Made pre-warm-up plan changes operate only against pre-configured plans (i.e. - when testing)
