Add publisher search and list filter

Description of your request or bug report:
Now that the publisher information is being pulled from Amazon, it would be great to use it in two places:

  1. Book search (though I suppose this might make more sense after some kind of advanced search is added)
  2. List filtering

For example, I read a lot of manga from the publisher まんがタイムKRコミックス and being able to easily view all the ones I’ve read together on my list would be very convenient.
