* when attesting late, use correct state / head
* don't send out obsolete attestations
* don't propose obsolete blocks
* remove some more resundant state updates :)
* simplify block logging (experimental)
* document fork choice division
* fix some Slot / Epoch conversion warnings

implement fork choice (#175)
* keep track of a finalized block
* keep track of all justified blocks
* use naive spec version of LMD ghost
* cache slot number and a few more things in BlockRef
* keep track of the latest vote of each validator
* depend less on the state of node.state (it's a cache, effectively)

initial state replay implementation
* fix initial attestation pool on reordered attestations
* simplify db layer api
* load head block from database on startup, then load state
  * significantly changes database format
* move subscriptions to separate proc's

* avoid rescheduling epoch actions on block receipt (why?)
* make sure genesis block is created and used
* relax initial state sim parameters a bit

Jacek Sieka 4670d6c98a naive attestation pool, in preparation of fork choice integration (#125)
* move attestation pool to separate file
* combine attestations lazily when needed
* advance state when there's a gap while attesting
* compile beacon node with optimizations - it's tooo slow right now
* log when unable to keep up

Zahary Karadjov 8f9a5441f1 More reliable network simulation
You'll need the latest versions of nim-eth-p2p, nim-serialization
and nim-json-serialization.

Before starting the simulation script, make sure to delete any previous
json files from the simulation folder:

```
rm tests/simulation/*.json
tests/simulation/start.sh
```

This should survive the creation of few blocks before diying with a
block validation error.

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
