Comment Field on CfP Form

[gnunicorn]

The CfP form misses a general Comment/"Something else I wanted to say"-field, allowing people to communicate anything that doesn't fit any other field given (like some availability problem, concerns and questions or questions/requirements for their talk).

I'd urge to add this field, because ppl that have things to say and don't know where to fit in the form will simply not submit the form – and so we will never know or be able to help them :( .
