Get title from data-original-title for links with popover

When using [popovers](http://getbootstrap.com/2.3.2/javascript.html#popovers) on links, Bootstrap removes the `title` attribute and re-adds it as `data-original-title`.

This PR will ensure that the title is still correctly set, when using popovers, by adding the modal title based on `data-original-title` if no `title` was found, and still defaults to "Are you ABSOLUTELY sure?"
