A new class to manage the list of loopers in a team. Provides the

functionality of the existing static BLooper functions (which now call
through to it) in a nicer package.  New code should use the global instance
of this (BPrivate::gLooperList) instead of the old BLooper functions (which
are officially deprecated).
