vbuterin 91a0c1ba5f Persistent committee size per slot reduced to max 128 (#734) 
* Persistent committee size per slot target 128 max 256

Cuts down the cost of verifying a shard chain and aggregating signatures for a shard chain, and also makes the shard chain signatures more usable by light clients for verification as they would only need to keep track of a max 256-sized committee.

Rename "vector" to "tuple" in SSZ spec (#794) 
To be done in combination with #777.

Also:

* Define "fixed-size" and "variable-size" more rigorously
* Use `"` vs `'` consistently
* Add missing `"`

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.
