support for Goodreads shelves/lists

Can you make it compatible with preexisting lists/shelves made by Goodreads itself?

There are also groups that create shelves as well:

UGH. So, of those 3 types of lists above, only one has an RSS feed, which is what the code uses now. I figured it would be easy to change the code slightly to add the group shelves. WRONG. Goodreads, for some reason, uses a different format for the RSS from groups, which means i can't reuse the parsing code. it's doable, just not as easy as I had hoped.

The other 2 types don't use RSS but it wouldn't be hard to parse the books out of the page.

Putting this on hold for now.
