Subject: [PATCH] startAutoRotate | possible improvement (#883)

* pannellum.js | possible improvement

startAutoRotate = function(speed, pitch, hfov)

Use case:

1. by using "getPitch()" and "getHfov()" as parameter you can just rotate your panorama with the current view.
2. if origHfov is set to a small value (eg. to start with a highlight inside a big panorama) you still can use startAutoRotate with a wider view

* Update pannellum.js
