Replace bitcoin with zcash in rpcprotocol.cpp
Not sure if this was intentionally left as bitcoin-json-rpc, but opening a PR for review in case someone wants to ACK and merge.
Document contributors to zcash
Release-notes.py generates release notes from git shortlog command when release version number is specified, and adds contributors to authors.md file. Can change the way this script works or where contributors are documented.

Improve joinsplit diagnostics
I don't advocate merging this for the hotfix release (to fix#1779) but this PR can be used to diagnose the real issue and should be merged ASAP afterward.
~I still need to add tests for `last()` and `element()` though.~ Done.
Issue #1851 shows that a zaddr->taddr can be rejected from mempools
due to not meeting fee requirements given the size of the transaction.
Fee calculation for joinsplit txs has not yet been agreed upon, so
during this interim period, this patch ensures joinsplit txs using
the default fee are not rejected due to an insufficient fee.
Process verification keys to perform online verification
Checking proofs involves some arithmetic with pairings using components of the proof and the verification key. If you already have some curve points, like those in the verification key, you can amortize the cost of some of the more expensive arithmetic.
This PR adopts libsnark's precomputation of G2 elements in the verification key.
We *currently* call `r1cs_ppzksnark_verifier_strong_IC`:
```c++
template<typename ppT>
bool r1cs_ppzksnark_verifier_strong_IC(const r1cs_ppzksnark_verification_key<ppT> &vk,
const r1cs_ppzksnark_primary_input<ppT> &primary_input,
const r1cs_ppzksnark_proof<ppT> &proof)
{
enter_block("Call to r1cs_ppzksnark_verifier_strong_IC");
r1cs_ppzksnark_processed_verification_key<ppT> pvk = r1cs_ppzksnark_verifier_process_vk<ppT>(vk);
bool result = r1cs_ppzksnark_online_verifier_strong_IC<ppT>(pvk, primary_input, proof);
leave_block("Call to r1cs_ppzksnark_verifier_strong_IC");
return result;
}
```
Notice that this merely performs precomputation of the verification key, and then calls `r1cs_ppzksnark_online_verifier_strong_IC`. This PR merely performs the precomputation during verification key initialization, and calls that function directly.
Closes#1833. Format currency amounts in z_sendmany error message.
Improve coverage of possible error states from z_sendmany.
Refactor qa test for z_sendmany operations.
