Avoid divisions by zero
...
Possible fix to avoid four cases of divisions by zero:
* `return state.validator_registry[index].effective_balance // adjusted_quotient // BASE_REWARDS_PER_EPOCH`
* `rewards[index] += get_base_reward(state, index) * attesting_balance // total_balance`
* `validator.effective_balance * min(total_penalties * 3, total_balance) // total_balance`
* `rewards[index] += base_reward * attesting_balance // committee_balance`

Custody game changes ( #866 )
...
* Custody game changes
1. Don't store the full chunk bits, instead only store a Merkle root. Increased history size complexity from `N` to `N + log(N)` but with the benefit of decreasing storage requirements from `N` to a single 32 byte hash.
2. `custody_bit` is computed as the first bit of the hash of the custody bits, not the xor. This allows us to more safely use functions with more risky security assumptions for computing the chunk mix.
* Update specs/core/1_custody-game.md
* Update specs/core/1_custody-game.md
* Update specs/core/1_custody-game.md

Clean up verify_indexed_attestation
...
Cosmetic changes:
* Add 4 lines of comments (now every statement has a comment)
* Avoid unnecessary `assert` (the end goal for me is for `assert`s to be exclusive to the operation processing helpers).
* Merge `return`s into one (increase readability, reduce verbosity)
* Use shorter-named `bit_0_indices` and `bit_1_indices` helper variables
Substantive change:
* Remove the condition that `len(0_indices) + len(1_indices) > 0`. This condition is redundant in the context of `process_attester_slashing` because of `slashed_any`. It is largely artificial in `process_attestation` where validators are incentivised to maximise new attestations.

Attestation committee refactor
...
* Remove `get_crosslink_committees_at_slot` (that function's ugly man...)
* Make the "base" that everything works off instead be `get_crosslink_committee`
* Attestations store epoch, start shard and shard, no longer slot (slot can be calculated from the other three)
* Retaining start shard in attestations allows `get_attesting_indices` to peek much further back into the past, making it useful for slashings (Phase 1)
* Some two-layer-deep nested loops become one-layer-deep loops
