Support GitHub Service Hooks

It would be nice to be able to support github service hooks. I have written this which we have been using for a while:

https://gist.github.com/1296623

If you'd be interested in getting something like this into your tree, that would be awesome. Currently we use it to show commit updates on all of our projects, and its great because its pretty instantaneous. I know you have the same features planned for Announce, so maybe something like this could be integrated into Announce.pm with an option to use postbacks, or poll.

Comece pelo gist GitHub service-hook vinculado e inspecione Announce.pm, que a issue identifica como um possível ponto de integração. Compare as abordagens de postback e polling solicitadas com o comportamento existente do módulo e defina o fluxo de hook compatível e os critérios de conclusão antes de alterar o código.
