IDN domains now read in their own alphabet

Releases#idn#website#seo

Internationalized domain names used to appear on this site the way registrars store them: as punycode. A page titled xn--b1afoeo.net tells a person nothing — the name is actually колев.net — and it tells search engines just as little.

As of today, every IDN in the catalogue is presented in its real alphabet:

Checkout is unchanged: offers, purchases, and escrow still transact the ASCII (punycode) form of the name, which is the spelling every registrar recognizes.
