This makes the comet mining code actually work. You can now run
king with `new --comet` to mine a new comet and get it on the
network. Mining appears to be significantly faster; I've had to
wait up to 20 minutes with vere, but I've never needed to wait more
than 30 seconds with king.
This retrieves the point data for not just the immediate sponsor,
but for the whole sponsorship chain. (For a moon: [galaxy star
planet], for a planet: [galaxy star], and so on.)
I booted a comet with vere, had it dump its keyfile, and then went
through `stack run king -- new` with that keyfile. Things were
fairly close, but there's still more to do here.
This fixes the turf uniqueness issue and makes us do less work for
things that vere didn't bother making real, like ownership
information.
This changes Pass to decode the Ed.Point directly in the type,
instead of having the packed Atom representation or raw ByteStrings.
Added conversion quickchecks and also decoded data off the Ethereum
contracts.
