* Refine Order for Web3 compat. & add conversions
Changed some of the fields in the Order class so that it can be passed
to our contracts via Web3.
Added conversion utilities so that an Order can be easily converted to
and from a JSON-compatible dict (specifically by encoding/decoding the
`bytes` fields), to facilitate validation against the JSON schema.
Also modified JSON order schema to accept integers in addition to
stringified integers.

Schemas were not being properly gathered into package installation.

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
