Improves the multikeyfile format by taking a single ship and a list of
life+key pairs, instead of a list of full seeds.
Also decouples these changes from the dawn event, once again putting a
single seed into it. In the multikeyfile case, keys are injected as
%rekey events to jael near the end of the boot sequence.
Haskell-side changes may or may not be incomplete, boot presently fails
at some unknown point with what looks like a noun conversion error.
This replaces the autogenerated bindings to the Azimuth contracts
which use Network.Web3 with hand rolled json messages. Booting a
ship involved 256 individual galaxy point lookups using web3, while
Vere batched all of that into one JSONRPC message.
With this patch, we also batch everything at each phase into one
JSONRPC batch.
