Changes for version 0.72 - 2014-10-23
- Bump Riap support to 1.2 (no longer produces v=>1.1 keys on info response). Note that we don't check riap.* keys on result metadata because they are only supposed to be produced by (network) servers, and this is an in-process (serverless) Riap client.
- Fix typo: unimplemented status is 501, not 502.
