Virtual visits, close #18

It improved MCTS, benchmark:

IsolaState state = IsolaState("___2___"
                              "_______"
                              "_______"
                              "_______"
                              "_______"
                              "_______"
                              "___1___");

vector<shared_ptr<Algorithm<IsolaState, IsolaMove>>> algorithms = {
    shared_ptr<Algorithm<IsolaState, IsolaMove>>(new MonteCarloTreeSearch<IsolaState, IsolaMove>(0.1, 0)),
    shared_ptr<Algorithm<IsolaState, IsolaMove>>(new MonteCarloTreeSearch<IsolaState, IsolaMove>(0.1, 5)),
};

Tester<IsolaState, IsolaMove> tester(&state, algorithms);
tester.start();

First MCTS had 0 virtual visits, second one had 5. Both had 0.1s per move. Result:
