* 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
