subs: change subdelay handling and vobsub timing

Browse Source 
Make subdelay handling work the same way for all subtitle types and
also allow changing subtitle delay to work better with vobsubs.
This probably breaks vobsub behaviour with timestamp wrapping though.

Positive values for sub delay now delay subtitles compared to video,
where before the effect was in the opposite direction.
