Add naration support

[GoogleCodeExporter]

Add the ability to provide a file full of timestamp-event pairs, which is
parsed in order to display subtitles/naration events in text on screen for
certain periods of time. 

Each even may have parameters which dictate how long it stays, what effects
it might have, where it is positioned, etc.

I respectfully disagree. While it would be a nice feature to have if it can be 
done
right, 1) it will lead to code bloat because it's impossible to please everyone 
and
2) there are already tools for video post-production.
