[mb-style] RFC: Artist 'is managed by' AR

[Matt Howe]

Pretty simple, most artists have a manager and we can't currently represent 
this in MB. It should be a link between a person and an artist/group. I'm not 
sure what else to say.....  any opinions on this?

Now that I think about it, aren't some artists managed by a company? I'm not 
really sure how a company can be represented in MB. Anyway...

Cheers,
