hiscore engine update: use binary mode for reading and writing and fread() instead of fgets() for reading hiscore data - fixes any game where a cr (0x0d) / lf (0x0a) is in the binary data (fixes galaga hiscores). secondly: check all memory areas for matching data, and apply all at once (fixes pacman and possibly more)
