Changeset 32110 for gs3-extensions

Message:

Forgot to commit bugfix. The bug was that when searching a solr collection, if you switch on a facet containing an apostrophe (try searching solr-demo for query term farm and then selecting the facet with apostrophe), there are 0 search results displayed for that facet despite the facet listing a positive number of matching docs for it. 1. Greenstone3SearchHandler.java and facet-scripts.js contain the fix. 2. GS2SolrSearch.java and SolrQueryWrapper.java just contain further debug statements, some commented out.
