Possibility to log changed slugs and redirect on 404

[wernerkrauss]

If a slug changes automatically, the link to the old page results in a 404, as the old slug is forgotten.

How about logging changed links to an extra dataobject (old link, new link) and hook in "onBeforeHTTPError404" like "OldPageRedirector" does?

This might be tricky for nested slugs. (e.g. /products//)
