Feature request: Mass updating redirection HTTP codes

[tomas-eklund]

During development, HTTP 301 redirects can become a major nuisance as they are cached in the browser. I've had issues with infinite redirection loops, automatically created redirects (URL Monitor) when renaming pages overtaking CPT archive slugs and other headaches.

It would be very nice if I could mass update the HTTP code for redirections, setting them to 302 (non-caching) during development and switching to 301 when everything looks solid.

I would also like an option to use 302 redirects for the URL Monitor.
