As noted in 8b48459c and www-api#150,
the format of events the site is expecting weren't full `h-card` or
`h-adr`s, which then broke the site's rendering.

Some files have changed a fair bit due to the pretty-printing formats
being different between Ruby (how we're writing these files) vs Java
(how they were mostly originally written).

This need change only in the way that the site renders, as events now
being submitted as a valid `h-adr` or `h-card` will be passed through
without inspecting.
