Jacek Sieka 4d55cf8eea beacon node sim: various improvements (fixes #111) (#156)
* allow running more or fewer validators
* use deterministic key generation for tests to avoid exhausting system
RNG
* update README with simulator docs
* write the data of each validator to separate file, instead of a big
chainstart.json (makes it easier to run different validator counts)

Dustin Brody 1cfea240ed Complete scan through v0.3.0 spec (#141)
* Complete scan through v0.3.0 spec; remaining known discreptancy is in bls_verify_multiple

* switch remaining slot-misuses of get_active_validator_indices to epochs

* spec workaround

* finish first 0.3.0 pass by getting slow, naive version of bls_verify_multiple running

* store tail block in database
* resolve unknown parents by syncing them from peers
* introduce concept of resolved blocks and attestations - those that
follow minimal protocol rules
* update state head lazily
* log more stuff
* shortHash -> shortLog
* start 9/10 beacon nodes by default, last can be started manually
* see also #134
* fix start.sh epoch length
