Release v0.2.2

Changed

• Member profile and CV pages on cast.cratis.io now ask search engines not to index them, since members have not opted in to having their personal data indexed. The home page and /join stay indexed. (#22)
• Member profile and CV pages on cast.cratis.io no longer publish job title, email, home town or interests in their structured data; those details stay on each member's own site. (#22)
