 Allow #8673

 Summery: PATCH to add the ability to override Walker_Category,
 Walker_CategoryDropdown, and Walker_Category_Checklist.

 The Comment Walker can be overridden by a user supplied object, and #8673
 added that capability to the page walker (Walker_Page) and the dropdown
 page walker (Walker_PageDropdown).

 Attached is a patch which adds the ability to supply your own walker
 objects for the category walkers. It uses the same method as for
 Walker_Comment (a instantiated class supplied to the wp_list_pages() or
 wp_dropdown_pages() function call.  I added a check to make sure the
 walker that's passed in is of the Walker class or has it as one of its
 parents.  That check isn't in other areas of WP, so if you want me to
 remove it I can.
