quartz: Fix Render and RenderFile

[Maarten Lankhorst]

This allows playing back ogg files, which don't work currently because
the source filter has multiple pins with a media type that has no
renderers known. This changes algorythm to try a direct connection
first, and if that fails, enumerate all filters that can use the input
type and tries to connect those, if that succeeds, it recursively
calls Render on all the output pins, if it fails it just aborts the
attempt and returns a failure.
