Implement default wishlist display as a views.module view

Issue Summary

Presently the main listing display of the wishlist module is hand crafted into the module. This was written before the views module was a part of the Drupal project. Last year I wrote custom configuration code to allow a site admin to enable/disable columns in that display, which is in a sense wasted effort.

The obvious answer I'd start with today would be to build a view in code for that page, and then build the page by calling out to that view twice - once for the list of public items and once for the list of private items. This would add a tremendous ability for you to customize your wishlist display, and some pending requested features would fall naturally out of the design.

I don't know that I have time right now to make this change. I'm pretty confident that I don't actually. Recently a few users have been submitting patches for baseline view support to the module. This issue is a call to see if you are willing to craft a patch that replaces the custom wishlist item lists with view based replacements.
