- Fix bug in Dialog#request where Promise was not being resolved properly with the received response to the outbound request.
- Srf#proxyRequest and Srf#request now return Promises when no callback provided, for consistency with other methods
- Added support for tagged inbound connections.
- Bundled functionality that was originally in the drachtio module; package.json now only requires drachtio-srf (i.e. do not include drachtio as a dependency).
