Bandcamp Importer: implement smart linking on album pages

[arsinclair]

When we're on an album page hosted by the label, currently we're corretly linking to that label on the right sidebar, however we're incorrectly displaying the artist link in the album title. The link looks like it's an actual link, but it's still the link to the label.

An improvement is needed in this area. I'm proposing the following flow:

• if the name of the artist album matches the name of the artist/label page it's hosted on, we can link;
• • if it doesn't match, we try to search in MB with aliases included (sometimes artists publish albums from their side-project on the same bandcamp page);
• • • if still no match, we don't link the artist.
• the script should respect the actual artist name used on the page and don't swap it with the artist/label, found by querying the Discography page URL.
• the script should respect artist name variations, and when importing an album where artist has been found and linked, we should use the correct Credited As name variation in the MB form.
