Changeset 29542 for gs3-extensions/solr/trunk/src/src

Message:

lucene sort order param has changed to reverse sort on/off, but solr uses asc/desc. I have moved the sort order param out of sharedsolenegs2fieldsearch and into lucenesearch and solrsearch so they can have different versions of it. added code to handle creating the param, and a properties file for the text strings. build.xml modified to copy the properties file over.
