clickAnchor() only stopPropogation if valid link

Running event.stopPropogation on all links was causing problems with other plugins (e.g. Bootstrap 3 Carousel direction links: https://github.com/miguel-perez/jquery.smoothState.js/issues/9).

Moving event.stopPropagation(); call into the shouldLoad condition resolves this.

Prevent clickAnchor() from running event.stopPropogation() if the link is not blacklisted
