AGI playback and hangup simplification

v0.5

I trust Twisted's stability

DTMF fix, more PyPI friendliness, and an IVR demo

v0.4.1

need MANIFEST.in for PyPI as well

DTMF event and string capture, plus easier Vagrant setup

v0.4

version 0.4

caller ID support for AsyncAGI origination

v0.3

version 0.3

now with asynchronous AGI support

v0.2

alpha is probably safe

first pre-alpha release

v0.1

ignore MANIFEST
