Allow us to click "Now Watching" shortly before the end of the current episode.

Right now, if you go to click now watching but trakt thinks you're still watching the previous episode, it won't let you click that. On the old trakt, you could click check in a few minutes before the end of the current pisode and it would work.

This margin of error helps in situations where someone skips intro or skips credits, or may not have clicked now watching at exactly the start of the episode, or perhaps have an episode where the runtime was not exactly right (30 minutes instead of 22 for example)

Probably a good idea to do this for movies as well as people will often skip the credits there as well.
