Location Listing Portlet ADT

Hi Russ,

I was able to implement ADT in the Location Listing Portlet. I made commits that follow the steps we've outlined in the ADT section of the APIs chapter. Seeing those indiv. commits should help you better see what changes a developer needs to make. I'll go over them with you Monday.

Note, the FreeMarker script (which you can browse and select when you manage the portlet's ADTs) is the .ftl file in the com.liferay...ect..dependencies package.
