Feature request:add ability to choose between listing Album Artists or Artists.

Scenario: in my album collection i have albums by a single artist, and also compilations and remix albums. 

Problem: in the banshee browser area, it offers a list of Artists, but what tends to happen is the list is not useful because compilations by various artists are sorted by Artist rather than the option to sort by Album Artist. This can be a particular problem if the album artist is X but one track has been remixed by Y, since Y shows up in the list of Artists, where i would want to hide artist Y from the list and only show the Album artist X. 
Additionally the Artist list gets cluttered and unwieldy,  and when you have compilations, you end up with many Artists in the list, often only related to one track each.
