v0.4.0

• Twilito now supports passing arbitrary arguments on as parameters to the Twilio API, converting snake_cased arguments into Twilio's CamelCased expectations. There are just too many possible parameters available in the API to deal with each explicitly in Twilito.
  • This shouldn't be a breaking change but is a conceptual shift in how Twilito deals with arguments, so it's a minor version bump.
• Updated tests to cover basic auth by including it in mocks.
