Start playing new video if cast session exist and new videojs player opened

[AleksanderSadov]

Currently if we start casting from one video and go to the other video and click play then cast session catches previous video and continues playing it. Expected behavior that if we start playing new video then it starts casting new media to existing session.

I am suggesting to add an option to the plugin (or even hardcode it) to start casting new video when another video was opened. The new media can be loaded on cast event "sessionJoinedListener" when we are joining existing cast session.

Let me know what you think on this issue. I am willing to add this functionality and create pull request.
