Toggle autostart and remember setting
We are using the autostart parameter to let videos player on page load (see http://support.jwplayer.com/customer/en/portal/articles/1428525-autostarting-on-page-load).
In most cases this will be the preferred setting for people using a WiFi connection. However, some people may want to turn this off, because they're using expensive tethering or data roaming.
How can we integrate an autoplay-toggle just as Youtube does it? And how can the setting be stored permanently for the user?
