Calling addRemoteTextTrack without explicitly setting the manualCleanup parameter to true is deprecated

Getting this error with the latest version of videojs

@aarvay thanks, some reason I am still not getting notifications for this repo.

I am going to fix this deprecation and set it to false.

I am going to be introducing a breaking change due to the move to emulated text tracks. Going to test this a bit before I do, but let me know if there are any other issues.

#25

Previously, you could get the track off the cue, but now you cannot—so I am leveraging the options so you have access to the same information.
