MVTR (MULTI VERSION TAG READER)

;MVTR (Multi Version Tag Reader ^^;) v1.0 by Seregon

;This snippet is for all those guys using dlls to retrieve id3v2 tags info ;)
;How to use:
;$idtag(path\file.mp3).title -> returns file's title
;$idtag(path\file.mp3).artist -> returns file's artist
;$idtag(path\file.mp3).album -> returns file's album
;$idtag(path\file.mp3).year -> returns file's year
;$idtag(path\file.mp3).genre -> returns file's genre
;$idtag(path\file.mp3).time -> returns file's length
;$idtag(path\file.mp3).kbps -> returns file's sound frequency
;$idtag(path\file.mp3).version -> returns id3tag version
;Documentation:
;www.id3.org -> official website
;www.id3.org/id3v2.3.0.html -> id3v2.3.0 structure
