v2.0.2-beta.0 - Geth Signature Fix

This is a fork of the upstream v2.0.2-beta.0 release that contains a workaround for interaction with geth. Geth interprets the r and s fields of signatures as QUANTITYs instead of DATA, as specified in the Ethereum RPC spec. Until this is sorted out, users who want to interact with a Ganache from go-ethereum generated signatures need to use such a workaround.
