### enableTouchActivity()
> Report user touch activity when touch events occur
> 
> User activity is used to determine when controls should show/hide. It's
> relatively simple when it comes to mouse events, because any mouse event
> should show the controls. So we capture mouse events that bubble up to the
> player and report activity when that happens.
> 
> With touch events it isn't as easy. We can't rely on touch events at the
> player level, because a tap (touchstart + touchend) on the video itself on
> mobile devices is meant to turn controls off (and on). User activity is
> checked asynchronously, so what could happen is a tap event on the video
> turns the controls off, then the touchend event bubbles up to the player,
> which if it reported user activity, would turn the controls right back on.
> (We also don't want to completely block touch events from bubbling up)
> 
> Also a touchmove, touch+hold, and anything other than a tap is not supposed
> to turn the controls back on on a mobile device.
> 
> Here we're setting the default component behavior to report user activity
> whenever touch events happen, and this can be turned off by components that
> want touch events to act differently.
