Respect parent path decision when cleaning paths.

When cleaning the video library and a source containing TV shows was unavailable,
choosing to keep it only kept the source root, while subdirectories were
removed.
The result was that TV shows "disappeared".

This is fixed by checking if there's a decision for the parent path when
cleaning the path table.

[PiSink] Dual audio support

The Pi supports dual audio in omxplayer, where the gpu outputs audio to
both hdmi and analogue connections.

With dvdplayer being more usable on Pi now, there are frequent requests
for this functionality through the Pi Sink.

This removes the gui setting for "dual audio" and creates a new sink
output for dual audio. It add support to the Pi sink and makes omxplayer
use the new setting.
