Renaming a page should change the slug and set up a 301 redirect

[boutell]

When a page is retitled, the slug should change, and the old slug should automatically become a 301 redirect. The 301 redirects table gets checked as a last ditch thing before issuing a 404 not found. That way if a new page comes into being and claims that slug, it wins; if an engine somehow covers that slug (less obvious), it also wins.

similarly, when you move a page via reorganize, it would be nice to rename the slug. Should this be added as a separate ticket?

Added #38

[boutell]

Still to do before I commit:

Make sure the redirect is a 301
Make sure a redirect can be updated if a newer page at that old slug is also renamed later
Implement child slug change cascade when a page is moved via "reorganize"

This is done.
