Copy album art to destination folder (without embedding)

[RollingStar]

Convert supports copying album art:

https://github.com/beetbox/beets/blob/1b187fbf5345727e0dfdaea958a714f19e917a4e/beetsplug/convert.py#L373

The function is called when a config is set for convert: copy_album_art. But this plugin only does embedding: it only references art.embed_item.

(Sorry for making more issues; I hope I'm not misinterpreting the goals of this plugin).

Thanks for the suggestion. I think this is a reasonable feature to have. @wisp3rwind, do you want to have a look at this since you added support for album art?

I'd also say that this is in scope of this plugin, but I won't have the time to look at it anytime soon, sorry.
