Add a status.json, maybe add dynamic space 'state' updating, list with spaceapi.net

[eidosabi]

There's a new database of hackerspaces, that includes a current state (i.e., open, closed) along with a lot of other possible info.

To be listed, there needs to be a status.json on the website. The JSON looks simple enough, but it needs to be automatically generated (e.g., on each status change in the space).
