upgrade apache solr from 3.1 to 3.6.2

Removed the apache-solr-3.1.0.war file and added the apache-solr-3.6.2.war file and changed the build.xml in webapp to use the new war file instead of 3.1.0.  This allows for improved search and fixes the wildcard issue in 3.1.

This update will require you to clear out by hand the deployed solr project until the changes from the restructuring branch are committed before deploying this for the first time.
