Added ability to modify liblocation

Added ability to modify liblocation for development frameworks, such as JSF, by allowing the addition of data-liblocation  to the description meta tag.

```html
<meta name="description" content="#{msg['termDescription']}" data-liblocation="#{request.contextPath}/resources/js/" /> 
```


 If data-liblocation is present, use it, otherwise use the default.
