Jacob Trimble a93eeca5db Add TTML-in-MP4 output support. 
This changes the default MP4 output to use TTML and adds a way to
choose which one is used.  This is done with 'format=ttml+mp4' or
'format=vtt+mp4'.

This also fixes the boxes output in WebVTT in MP4.

Jacob Trimble 4766654b4d Add TTML text output. 
This only supports TTML output; meaning the user can convert WebVTT
into TTML, but not the other way around.  This will be useful for
DVB-sub subtitles that would be better supported within TTML.

This only adds text-based output; a follow-up will add MP4 support.
