Python SDK - Bot Engine integration

Bot Engine integration

Breaking changes:

• the message API is wrapped around a Wit class, and doesn't take the token as first parameter

Python SDK - Rewrite in pure Python

Breaking changes:

• audio recording and streaming have been removed because:
• many people only needed access to the HTTP API, and audio recording did not make sense for server-side use cases
• dependent on platform, choice best left to developers
  • forced us to maintain native bindings as opposed to a pure Pythonic library
• we renamed the functions to match the HTTP API more closely
  • .text_query(string, access_token) becomes .message(access_token, string)
• all functions now return a Python dict instead of a JSON string
