[Patch] Phonon: add 2 methods to Path

[Tanguy Krotoff]

Hello again

Here is a very small patch that adds 2 methods to Phonon::Path:
MediaNode *Path::sourceNode() const
MediaNode *Path::sinkNode() const

This is useful when manipulating several MediaObject/AudioOutput/...,
then you don't need to keep track of everything yourself, Path does it
for you:

	Phonon::MediaObject * mediaObject = new Phonon::MediaObject(this);

	QList<Phonon::Path> outputPaths = mediaObject->outputPaths();
	foreach (Phonon::Path outputPath, outputPaths) {
		Phonon::AudioOutput * audioOutput = dynamic_cast<Phonon::AudioOutput
*>(outputPath.sinkNode());
		if (audioOutput) {
			//blabla
		}
	}

I don't really understand why this 2 methods where not already there.

So if someone could simply tell me if it is OK or not...

Thanks in advance
