You may have noticed that when you click on the add review, or the number of reviews link, the Reviews tab opens.
The problem is though, that especialy in mobile devices, the tab content might be out of screen, so although the customer clicks the link, he doesn't see any change, and he is left with the impression that the link does not work.
This modification, gives a smooth scroll to the point where the tabs begin, showing the content of the reviews tab.
This modification is tested in the default opencart theme, and also in Joomla&Opencart versions.
