bump samba for darwin from 3.6.0 to 3.6.12
[rbp] Fix for broken ASS subtitles.

The video fifo patch broke some types of subtitles including ASS.
This keeps closer track of when the sleep time would have ended and calls FlipPage at the appropriate time.
I've also removed the 500ms in the sleep time calculation as that makes the subs render 500ms late. Not sure what its purpose was.
Fix the result of Player.GetProperties with param "currentaudiostream" for video without an audio stream (index = -1).

Fixes access to samba server running on osx 10.7 and later (was worked around by custom samba package via smbup which is superseeded by this).
