Adding support for song info

Considering how many people tend to ask questions regarding what track is playing for the current boss, would be neat if "sound_bgm" could add 2 more Kv's to allow manually adding tags to show song info.

Would save a lot of people of a major headache if FF2 would just print out the song info as soon as the theme starts playing.

Something like this:

    "sound_bgm"                                                    //Background Music
    {
        "path1"        "freak_fortress_2/daftpunk/daftpunk_bgm.mp3"    //path to 1st track
        "time1"        "291"                                            //length of 1st track
        "name1"        "{orange}Technologic{default}"                    //1st track name
        "artist1"      "{blue}Daft Punk{default}"                        //1st track artist

        "path2"        "freak_fortress_2/daftpunk/daftpunk_bgm2.mp3"
        "time2"        "246"
        "name2"        "{orange}Around the World{default}"
        "artist2"      "{blue}Daft Punk{default}"

        "path3"        "freak_fortress_2/daftpunk/daftpunk_bgm3.mp3"
        "time3"        "224"
        "name3"        "{orange}Harder, Better, Faster, Stronger{default}"
        "artist3"      "{blue}Daft Punk{default}"

        "path4"        "freak_fortress_2\daftpunk\08_get_lucky.mp3"
        "time4"        "248"
        "name4"        "{orange}Get Lucky (feat Pharrell Williams & Nile Rodgers){default}"
        "artist4"      "{blue}Daft Punk{default}"
    }

This could also be worth a shot: https://forums.alliedmods.net/showthread.php?t=105816

2nd option would work best if boss themes already has ID3 tags applied, as that extension would auto-grab the appropriate tags with the natives it provides.
