Paul Davis 0f63b82943 fix error in multiple calls to SourceFactory::createWritable()
removal of tape tracks removed an intermediate argument in the argument list; presence of default args for the
last two arguments and implicit conversion from int->bool prevented the compiler from complaining
about any existing calls.
