Students who are hearing impaired need to see closed captioning during a presentation
and the playback.

Add a new function for moderators to open a Transcript Window that enables them to
type in text for closed captioning (see attached image)

When the Transcript Window is active by one (or more) moderators, viewers will see
a new button on the toolbar 


When the click the CC button, a new window will open showing them the close captioning
text ("CC text").


The CC test is stored along with the other elements of the recording in the events.xml
with a time stamp.


When the presentation scripts runs to process the recording into a playback file, it
will scan and process the CC text and display it in the playback (likely below the
presentation area).
