This release resolves issues around https://tools.ietf.org/html/rfc7591 and system secret generation.

This release introduces the following breaking changes:

• The system secret is now generated correctly. This will break your JWK store in RethinkDB. You will probably need to remove the jwk table from RethinkDB. Hydra will generate all required keys itself, next time you start a hydra instance.
• The client HTTP API now takes scope string instead of scopes []string. Example: { "scope": "photos openid email" }. This change affects RethinkDB as well
