[CGMZ] Battle BGM Control - Version Beta

Hi all, today this plugin was updated to version Beta!
This version adds statistic tracking for BGMs played via this plugin. You can now know things like how many total BGMs were played via this plugin, which file was played least/most and how much it was played, and the play count of each specific bgm track.
This data is available via Plugin Command which was also added in this release. See documentation for usage.
