spec updates (#39) 
* some minor renames
* fix some leftover block slot references (replaced by state slot)
* fix some more uint underflows
* update epoch calculations (reward et al)
* now works past 100 epochs at least with empty blocks (very slow)

spec updates (#34) 
* spec updates

* make several constants uint64 to help minimize casting

* change comment style on fields and constants to make room for better
comments
* add BLSVerify and BLSAddPbkeys facades to insulate spec code from
milagro
