Review request for Asterisk Developers.


app_swift uses the Cepstral text-to-speech engine and copies audio frames straight from the Cepstral libs to the call channel which avoids the need to write the generated audio to a file first and then read it. Additionally, DTMF recognition code was integrated into the module to prevent delays in previous usage scenarios where the app was called and dtmf listened for afterward.

I've built against trunk successfully now (thanks to Tilghman for getting the build tweaks squared away) without any errors and made dozens of test calls using different usage scenarios.
