Poor Man's UserVoice

As many of you I've often found the "Feedback" side tab provided by UserVoice and similar services on the web. And many times, as it often happens, I wondered about a freesoftware alternative.
Until the day I needed it, but had no time to implement by myself.
So, as a light and dummy solution, I've hacked the "VoiceHub" script.

It is a self-contained PHP script: when invoked on HTTP GET it outputs a Javascript file to generate a simple sliding dialog with a form, when invoked on HTTP POST (so: when the generated form is submitted) it creates a new issue on the configured GitHub repository.

I've published a minimum viable release and a dedicated web page with some instruction, but more is coming as soon as I will begin to massively use it on my own projects.
