81d5becc7b Switch hash functions, prevent underflow & verify that shuffling works (#149) 
* prevent balance underflow, per spec implementation note

* verify that permutation shuffing works: add YAML dependency to be used for ingesting test cases; switch from blake2 to keccak256 to match EF test cases; remove inefficient naive-spec-version of shuffling algorithm now that protolambda's can be tested directly

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

add initial block pool (#139) 
* implement in-memory block graph
* 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

2d52d5cbfe convert some asserts to doAsserts to keep them in release mode builds; rename get_initial_beacon_state to get_genesis_beacon_state to track spec; switch target spec version to 0.3.0; switch references to penalize_validator to slash_validator/slashValidator to track spec; make some function returns safer by omitting 'return' (#132)

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