13c7f7fcec begin refactoring 0.5.0 epoch transition (#185)
* begin refactoring 0.5.0 epoch transition at justification and finalization

* update processTransfers to 0.5.0 spec

* update get_crosslink_committees_at_slot to 0.5.0 except for noted workaround for pre-0.5.0 spec bug related to epoch boundary conditions, to be flipped in more coordinated way with other epoch processing changes

* mark ejection processing as 0.5.0

* 0.5.0 epoch update finalization

* rm BEACON_CHAIN_SHARD_NUMBER to complete updating miscellaneous constants to 0.5.0

* mark verify_slashable_attestation as 0.5.0

* update process_attester_slashing to 0.5.0

* update process_slashings(...) to 0.5.0 and mark process_exit_queue as 0.5.0

* refactor epoch processing by implementing 0.5.0's update_registry_and_shuffling_data(...)

f36c2d86dc begin 0.5.0 spec update (#179)
* begin 0.5.0 spec update: parent_root -> previous_block_root, BeaconState.justified_epoch -> BeaconState.current_justified_epoch, DOMAIN_PROPOSAL -> DOMAIN_BEACON_BLOCK, temporarily rename BeaconBlockHeader to BeaconBlockHeaderRLP to allow for gradual re-merging without disrupting RLP; mark a few unchanged functions and data types, implement get_temporary_block_header/get_empty_block/should_update_validator_registry/processBlockHeader/cacheState; update a few others

* a dozen or so more trivial mostly comment changes, finding more unchanged parts of 0.5.0

* several more trivial changes; goal is to reduce noise around the upcoming substantial changes (epoch processing, etc)

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
