Redirects and 404 monitor

Sets up forwarding from an old address to a new one, so that after you rename a category or move the shop, visitors and search engines land where they should instead of on an empty page. A rule can cover a single address or a whole section, separately for each storefront or for all of them at once. There is also a list of addresses where visitors hit a missing page: you can see which ones happen most often and create a redirect right from there, with a suggestion of a similar working address.
