bingo: fix the JSON-LD place markup

Browse source 
Each Place carried its info_url as sameAs, but sameAs means "this is
the same entity", and the URL is an operator page or news article
about the datacenter. Use subjectOf with a CreativeWork instead.

Incidents were missing from the structured data entirely. Add them as
Events at the place (name, start date, source URL), and give the
ItemList a dateModified.
