#9383: Allow get_pages to exclude by slug in addition to id

 Currently, get_pages() allows template authors to exclude certain pages
 from the result, by their ID. It's more useful to exclude by slug when the
 IDs aren't immediately known.

 For example, on a WordPress site I recently made, I coded an
 automatically-generated menu listing the site's pages and their subpages.
 There are certain classes of pages I want to exclude, and hard-coding the
 page IDs into my menu code just isn't a good way to do it. Excluding by
 page slug works beautifully.

 '''Patch:''' I've included a patch to add this functionality. It is a very
 short addition to wp-includes/post.php (one new line and two altered
 lines), has been well used on my (now live) site, and adds a very useful
 feature.

 '''Syntax:''' The syntax is identical to the old use, except that where
 the "exclude" parameter only accepted numbers, it now can take strings. If
 the value given is not a number, it's treated as a slug. If it is a
 number, it's treated as an ID like before. For example:

         $subPages =
 get_pages('hierarchical=0&exclude=sidebar&parent='.$page->ID);

 will get subpages of $page that don't have the "sidebar" slug. (Numerical
 values are still treated as IDs, and lists can contain any number of IDs
 and slugs to exclude.)
