Justin fad9b4672a
Disallow transfers 
As discussed in yesterday's call, temporarily disable transfers until the network is deemed stable enough. We can consider doing a "test-run hard fork" changing this constant prior to the phase 1 hard fork.

Simplify get_justification_and_finalization_deltas 
Cosmetic changes related to `get_justification_and_finalization_deltas`:

* Review naming of misc helper functions and variables
* Abstract away common logic and rework for readability
* Add `MAX_FINALITY_LOOKBACK` and `BASE_REWARDS_PER_EPOCH` constants
* Rescale `INACTIVITY_PENALTY_QUOTIENT`

Substantive changes:

* Make logic relative to `previous_epoch` throughout (as opposed to mixing `current_epoch` and `previous_epoch`)
* Replace inclusion delay bonus by an inclusion delay penalty

Remove serialization from consensus 
Consensus now only cares about Merkleisation (i.e. `hash_tree_root`), not about serialization (i.e. `serialize`). This simplifies consensus code by a few tens of lines, is conceptually cleaner, and is more future proof.

A corresponding change is required in the deposit contract.

Possible aesthetic rework to get_domain 
In general I dislike how domains, which should be an unobtrusive out-of-the-way thing that we don't think about much, are taking up so much space in code to express, to the point of them being the single thing preventing `bls_verify` from being expressed in one line of code. Here I reorder arguments and add a default, and make `bls_verify` a one-liner.

Not necessarily convinced that exactly this approach is the way to go, but IMO it's worth considering.

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).

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)).
