Redirect .bit domain in URLs to real site address

**Is your feature request related to a problem? Please describe.**
Related to link breaking (i.e. when clicking on a old link and the origin has changed)

**Describe the solution you'd like**
When a user visits `ZERONET/somesite.bit/page?query` the browser gets a redirect to `ZERONET/siteaddress/page?query` to ensure that if the users copy the URL and he posts it somewhere, years later the links points at least to the same site (obviously the content may have gone, but at least it won't point to some other site as is currently doing `zeroblog.bit` and other `.bit` domains that have expired meanwhile).

Go visit http://127.0.0.1:43110/zeroblog.bit/?Post:5 to see if it is what you think...

I think this breaks the links that many people have spread in the whole ZeroNet in a crappy way: I can stand the content being removed from site owner or the site not being served anymore (which are just physiological, for example if noone is interested in such content) but not the URL pointing now to some other content just because of the renewal rules of Namecoin...

Also the only harm the proposed solutions does is to make URLs more "ugly" but I think it is worth the added benefit of referential integrity... I'd also like to see other opinions on the topic
