They currently always show as "Seconds ago", presumably due to the fact that their pubdate parses as 0.

When the domain supplied in Pirata::Config::BASE_URL is returning bad results, check if it is a 502 gateway error (usually through cloudfare) and give some sort of indication to the user.

Nokogiri is used minimally, but it is a huge drag due to native extensions (especially for first-time installers). Would be great to replace it with stdlib XML parsing or [Oga](https://github.com/YorickPeterse/oga)
