Keep all sounds and tones within the ttyclicks module.

Having tried for 5 years, I have officially given up on getting
any additional sounds or tones into the kernel.
I think they belong there, but can't convince anyone else.
So they will stay forever in my ttyclicks module.
That means you can pretty well ignore the kd patches in the patch directory,
they will become out of date and I won't be supporting them.
