Throw and handle errors from Providers.
In web3 wrapper when a response contains an error field we throw this rather than return response.result which is often undefined. In Signature Utils we handle the error thrown when a user rejects the signing dialogue to prevent double signing. Exposed the ZeroExTransaction JSON schema. In Website only use the MetamaskSubprovider if we can detect the provider is Metamask
