Move to SHA256
...
SHA256 is de facto blockchain standard. Standardisation of the hash function is a prerequisite for [full standardisation of BLS12-381 signatures](https://github.com/ethereum/eth2.0-specs/issues/605 ). Blockchain projects are likely to provide a cheap SHA256 opcods/precompile, and unlikely to provide a Keccak256 equivelent. (Even WASM-enabled blockchains are likely to provide a SHA256 opcode/precompile since WASM does *not* natively support optimised SHA256 CPU instructions.) With Ethereum 2.0 embracing SHA256 the wider industry is more likely to converge towards a unified cross-blockchain communication scheme via Merkle receipts.
There are no security blockers with SHA256 (see comments by Dan Boneh [here](https://github.com/ethereum/eth2.0-specs/issues/612#issuecomment-470452562 )).

Change get_shuffling to compute_committee
...
See #729 and #774
The behavior now is that the first committee will consist of `get_permuted_index(0..n-1)`, the second committee `get_permuted_index(n....2n-1)`, etc.

Fair proposer selection probability
...
Note that as a side effect, proposer selection becomes less predictable, but I don't feel like this is a large downside.
