[arch-general] Add "phonon-xine" to KDE deps?

[Sven-Hendrik Haase]

Hey,

I've found that I hardly get any sound at all in KDE without the
phonon-xine package installed since KDE 4.3. I wondered if this is a
general thing or if it occurred to me just because my installation is
rather old. If it is generally needed, why not make it a dependency? Or
should I not require it at all and it is a misconfiguration on my side?

Insight appreciated :)
