Due to increased size of MAX_SEGMENTS old savegames became incompatible. To compensate added MAX_SEGMENTS_ORIGINAL with the original segment amount and read certain savegame info with this info when dealing with standard-sized levels and use Highest_segment_index when dealing with larger levels which are incompatible with older versions of the game anyways. Makes savegame site more efficient and still maintain backwards compability
