New extension proposal: festival

Hello pecl, Some while back while trying to learn to write extensions I chose to write one to interface with the festival text to speech synthesiser library http://www.cstr.ed.ac.uk/projects/festival/. It was fun to test. I would now like to list it on pecl to make it easier for people to find. The extension is a C++ one and uses the API described here http://www.cstr.ed.ac.uk/projects/festival/manual/festival_28.html#SEC132 The code is hosted on github https://github.com/natmchugh/festival . It would nice if somebody could take a look. Any comments on stuff I have done wrong or missed would be gratefully received. Thanks Nat
