sub: offset subtitle timing to video start PTS

Browse Source 
This allows using external subtitle files with e.g. transport stream
files that don't start at time 0.

Note that if the .ts file has timestamp resets, everything goes south.
But I guess this was already the case before, unless there are external
subtitle files that also include timestamp resets, which is unlikely.
(On the other hand, you could for example expect that it works with
embedded DVB subtitles, that were somehow captured from the same stream
and use the same timestamps.)
