RelatedContentPortlet.java
Log Message:
CMSC-959 - Added two new methods. The first: getElementIdFromContentURL uses a
regex to try and find a elementId in the request URL generated by a contentURL.
The second is just a convenience method: getElementId, that has protected
scope. This allows you to extend and override the portlet class and make your
own implementation to get an elementId.
