New GPIR Service URL for GPIR Portlet

The old TeraGrid GPIR service is being retired and replaced. To point to the new server, edit GPIR's portlet.xml file and replace

http://alpine.tacc.utexas.edu:8080/gpir/webservices

with

http://laredo.tacc.utexas.edu:8080/gpir/webservices

To rebuild this portlet, use the command "mvn clean install -f portlets/gpir-portlet/pom.xml" from the "ogce-portal-only" directory.
