--trackdb_legacy.lua
--loads the (old) track database. the only use for this is to provide data for rails that haven't been written into the ndb database.
--nothing will be saved.
--if the user thinks that he has loaded every track in his world at least once, he can delete the track database.
--trackdb[[y][x][z]={conn1, conn2, rely1, rely2, railheight}
--trackdb keeps its own save file.
