get cue track when load m3u playlist

can't load it correct when save a playlist contian music track in cue sheet under xbmc. xbmc treated the whole flac/ape file as one song when load playlist now. and in fact it contian an album.
I'll add a comment. 
and I have tested again and sure SetProperty("item_start", iStartOffset) is need to let songs from the same ape play at right startoffset.
