Bug Fix: Fix output logging, switch log method

Browse source 
Output logging, a debugging feature that is only enabled at build time
if I need to chase down some audio mixing or output bug, was not logging
anything at all. Change to use Cocoa file writing methods, and actually
implement the output writer function again.

This code is left disabled 99% of the time anyway, and especially in
release builds. Like the node logging code elsewhere, it has the
potential to be very noisy and consume massive amounts of disk space.
