Put all the faces in the ivy-faces group (and also faces)

[hmelman]

Because of the line

    (setcdr (assoc load-file-name custom-current-group-alist) 'ivy)

four of the ivy faces are listed in the ivy custom group rather than the ivy-faces group.
This seems wrong to me, shouldn't all the faces be in ivy-faces?
Also, I think the ivy-faces group should also be in the faces group.

So I'd first do the defgroup for ivy, then list all non-face defcustoms
Then define as follows:

    (defgroup ivy-faces nil
      "Faces for `ivy."
      :group ivy
      :group 'faces)

and then list all the deffaces.

Thanks, it looks like I started doing it to get things more organized, but didn't finish.
