Updates the url so that it contains "?t={time}" corresponding to video.currentTime. Sometimes Youtube opens a video with a t parameter, but it doesn't get updated and when you refresh you go back to that time instead of where you left off.

Sometimes Youtube opens a video with a ?t= parameter, but it doesn't get updated and when you refresh you go back to that time instead of where you left off. Also, when reloading, it doesn't
resume exactly where you left off. This script updates the url each time you pause the video.
Feel free to use the timeupdate event instead of the pause event (floods browser history) or sessionStorage (the video loads at 0 and then moves to
video.currentTime = sessionStorage.getItem('seconds'), not as smooth as changing the url request).
