Changeset 32430 for gs3-extensions/solr/trunk/src

Message:

solr should only be accessible locally (from localhost, specifically 127.0.0.1) which means over http. This conflicted with the previous design of the properties file for working with http and/or https. Now we have tomcat.port.https and localhost.port.http, both always set. In place of server.protocol that used to contain the default protocol, we now have server.protocols which can be set to a comma separated list of one or both of http and https. Drastic restructuring followed. I think I've tested all but https certification stuff.
