Make page slugs and usernames separate monsters

Currently, if a nation has a user named 'kitten', then the nation can't have any pages slugged/stubbed 'kitten' -- can we remove that restriction?

Official response from Jim Gilliam

The simple way to deal with this is to just remove the username "kitten" from that person.  You can do this from the "Public profile" tab on the person's record in the control panel.

It was a fair amount of work to allow people to have /username, which I think is a great feature, much more desirable than /user/username.  And since it's so easy to reclaim a slug, I'm inclined to leave this feature as is.

option to hide nav item from unauthorized user

we'd like an option to only display links in the top nav that the current user has permission to see. currently if a page is set to be visible to certain roles only but also visible in the top nav, anyone can see the link in the nav. we get the value of displaying all links in some cases (link piques interest, may encourage signups), just seeking a workaround for other cases (easy access to some supporter-only nav item). thanks!

Pagination for dynamic lists of non-blog pages

Several clients have had a need to list a large number (50+) of non-blog-post pages.  The current methods for including lists by subpage or tag don't allow for pagination and only output 30 pages (please correct us if we have that wrong) , so there's currently no way to dnamically list pages beyond 30. If we could pass a paginate tag into the template display, that would be extremely helpful.
