[Feature Request] Ability to edit id3 tags

[borekon]

There's another music player on the store that has a plugin that can edit id3 tags. It woul be fantastic to add such feature to this player.

According to an email from Maximilian Frank: " it could be helpful to add mp3tag.js.org as pure-javascript plugin, which can read and edit ID3 tags."
