* Fix bug in ERC721 balance query
Was using method balanceOf(), but needed to be using ownerOf().
getERC721TokenOwner() method lifted from
@0x/extensions/contracts/src/OrderValidator/OrderValidator.sol
* Reuse new en/decoders; avoid abi.decode().

* Don't use dockerized solc for ERC20 contracts
Because they demand solc version 0.4.26, and it seems as though the tag
for that version has been deleted from dockerhub.
Without this, @0x/contracts-erc20 was failing to build.
* Rename batch functions to use plurals
* Skip dockerized solc for contracts needing 0.4.26
I seems as though the tag for that version has been deleted from
dockerhub.
Without this, these contracts were failing to build.
* Make revert reasons follow snake case convention
