Allow microfades when changing graph about theamazingaudioengine HOT 7 CLOSED

This also applies to removing channels. When a channel is playing (ie: looping ambient audio) and is removed it can cause a click. Attempting to ramp the volume of the channel down before removal doesn't seem to help. Note that the channel in question is an AEAudioFilePlayer playing an uncompressed, small, looping wav file.

Another potential fix for this problem would be the ability to re-assign the file that the channel is playing instead of having to remove and recreate it in these circumstances.

Would adding the channel to a group and adjusting the volume of the group possibly be a work-around? So the removal of the channel is done when the group is essentially muted?

Initial tests seem to indicate that putting a channel removal behind a channel group with its volume set to 0 causes the click to not occur.

This is due to #22, which I'll fix soon.

Is this still a problem, Joe?

I have not heard it lately but also been focusing on other parts of the app - once I get settled back I will look into it and report back.
