4.4.9 Search on position

The program will search for games with exactly the same position as the one on the chessboard. Rebel will automatically recognize move transpositions, if relevant. This means that games started with "1.d4 d5 2.Nf3" and "1.Nf3 d5 2.d4" are the same to this search function. This function is very useful for opening preparation.
