Merge #272: Expose JsonOutPoint

158e7a0 Expose JsonOutPoint (Casey Rodarmor)

Pull request description:

  I'm implementing an in-memory dummy Bitcoin Core RPC server for testing. Exposing `JsonOutPoint` is necessary in order to implement `lockunspent`, which takes `JsonOutPoint`s instead of `OutPoint`s.
