spec updates (#34) 
* spec updates

* make several constants uint64 to help minimize casting
* document data type woes - will have to revisit these
* change comment style on fields and constants to make room for better
comments
* add BLSVerify and BLSAddPbkeys facades to insulate spec code from
milagro
* fix proof of possession type
* drop explicitly ordered container fields from ssz - there's an issue
open to sort this out before committing it to the spec

Signature aggregation in block processing (#5) 
* signature-aggreg-in-block-processing

* Message is a Blake2 hash not simple concat

* Address comments:

- Range change in parent_hashes computation
- Slot not beind module Cycles anymore
- justified_slot part of the hash
