c141d90f0f Fix typo with initial generation of latest_penalized_exit_balances 
The spec as written is not valid python -- the generator of the list
comprehension must be iterable.

It looks like the author simply meant to `range` over the intended length.

This commit fixes the missing `range` operator

* Avoids unnecessary hashing of `message`
* Makes the ordering of arguments (`message` followed by `domain`) consistent with usage order

4cf06d908a Truncate the index into the Merkle tree to bytes[8] 
The beacon chain expects a `uint64` in part to avoid big-int computation.
This commit updates the `Deposit` log so that it broadcasts data of the
appropriate size.

b25154c774 Correct references to sig scheme in beacon spec. 
BLS is the name of the signature scheme and BLS12-381 is the name of the
curve that it is defined over. So it is more correct to talk about a
"BLS signature/pubkey" rather than a "BLS12-381 signature/pubkey".

6f5a865508 Reorder type so the ssz serialization matches other uses 
There is an order based on the Vyper deposit contract which should be maintained
here. There is also a reference to it when processing `Deposit` messages.

This commit corrects the order here so all serializations will match.

dff84c00b0 Fixes bugs with description of deposit verification. 
1. The order of the `deposit_data` serialization does not match the current
Vyper contract. The description now matches that serialization.

2. The `deposit.merkle_tree_index` was not being used (at least explicitly) so
the text now reflects which inputs are to be used for which parameters in the
pseudocode spec that follows.

3. There seems to be a bug where we want the initial leaf to be the `hash` of
the `DepositData`, not the data itself. The text now reflects this requirement.

994a42e6b1 Add getter to Vyper contract for Merkle branches 
Returns the Merkle branch for the leaf at index `index`. This getter provides
an alternative way for beacon chain proposers to access the Merkle tree of
deposits rather than being Ethereum 1.0 light clients. The method can be
called on a trusted Ethereum 1.0 archive node at specific past block numbers
to retrieve the Merkle branch needed to register a validator.

b78458bbb2 Removes naming conflict in get_shuffling. 
The variable name 'slot' in the for-loop in 'get_shuffling' conflicts with the get_shuffling argument name 'slot'. Renames 'slot' in for-loop to 'slot_num'.
