Replace committee exponential backoff with max progress 
Removes the mechanism that only rotates committees if blocks have been finalized and every shard has been crosslinked or at exponentially decreasing intervals, and replaces it with a rule that shard committees can only progress a maximum of 64 epochs at a time to preserve the invariant that maximum possible work required per epoch for a validator is O(1).

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.

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)).

Fair proposer sampling 
I think we want `first_committee[epoch % len(first_committee)]` as opposed to `first_committee[slot % len(first_committee)]`. The reason is that if the shuffling happens infrequently and `len(first_committee)` is a multiple of `SLOTS_PER_EPOCH` then the proposers will not be sampled fairly.

Taking this logic further, we may want to avoiding always picking the proposer from `first_committee`, e.g.:

```
    validators_at_slot = []
    for crosslink_committee, _ in get_crosslink_committees_at_slot(state, slot, registry_change):
        validators_at_slot.append(crosslink_committee)

    return validators_at_slot[epoch % len(validators_at_slot)]
```

Unfortunately not simpler than before, but moves challenges outside of the validator records and so keeps validator records constant-size.

Does NOT handle Deposit transactions because that is a special case for which I recommend a deeper change (will do this in another PR soon).
