When we are using a screen reader to read a page where is a link generated by ATag taglib, the text 'Opens new window' is read twice.

Looking into the taglib code, we can see the information is being duplicated in title and a span label inside the content.

Steps to reproduce
1.- Start Liferay (master)
2.- Add a portlet (i.e. bookmarks)
3.- Go to Configuration --> Sharing --> Facebook
4.- Inspect the HTML associated to the link with text "Get the API key and canvas page URL from Facebook"

Expected Result
The information about the link will be opened in a new window appears once.

Actual Result
The information about the link will be opened in a new window appears twice:

<a href="http://developers.facebook.com" target="_blank" title="(Opens New Window)">Get the API key and canvas page URL from Facebook. 
	<span class="sr-only">(Opens New Window)</span>
</a>
