Breaking Change in build_request? #119

Issue Summary

Prior to #95 being merged, we had code like the following that worked:

sendgrid.patch(request_body: an_array)

This worked because an_array would, along the way to Net::HTTP, be encoded to JSON. #95 changed this behavior, as now only hashes are automatically JSON-encoded.

Was this change in behavior intentional, or was our usage unexpected?
