Patch to "wp_list_pages" to add the opposite of "exclude" (called "only")

[Fryfrog]

The diff below will add the opposite functionality of "exclude" to the wp_list_pages. This means instead of excluding all but 1 page, you can choose to ONLY show that one page. This way, no matter what you add in the future it will never have to be messed with to exclude it.

Added it into a code block to make its formatting "nicer"

Thanks! I can't tell you how many people have asked me if this was possible.

patched against 1.6 snapshot

Works for me.

This ticket is resolved by changeset:3655 that added the ability to include a selected page or pages in function get_pages(). So, with wp_list_pages(), a parameter of 'include=3,4' will present just pages IDs 3 and 4.

Guess it's okay to change this to fixed even though it is assigned to Mark, and request bg's mark as Closed.
