1. listpeers has a deprecated `"closer": null`, which we need
to handle in the schema, while trying not to damage our
documentation too much.
2. Don't print a condition if there are no fields to print.
3. Allow a special "untyped" marker for multifundchannel which returns
arbitrary JSON in a field.
4. Allow a single field return (for 'stop').

The idea is that you regenerate the man pages in the same commit you
alter them: that's how we know whether to try regenerating them or not
(git doesn't store timestamps, so it can't really tell).
Travis will now check this, so force them all to sync to this commit.

ChangeLog-Added: New `getsharedsecret` command, which lets you compute a shared secret with this node knowing only a public point. This implements the BOLT standard of hashing the ECDH point, and is incompatible with ECIES.
