remove xslt sort for solr search results in case someone actually specifies a sort field in the query. https://projects.ecoinformatics.org/ecoinfo/issues/3397
clean-up the solr results XSLT to display more pertinent fields (many paths have been collapsed into single fields, etc). Added an abstract snippet in the search results (140 chars). https://projects.ecoinformatics.org/ecoinfo/issues/5916
rename resultset template to include "solr" so that it can co-exist with the original pathquery-based resultset template (NCEAS skin approach that has one style sheet for multiple document types)
Allow use of server-side XSLT for SOLR queries that include "wt=<qformat>". https://projects.ecoinformatics.org/ecoinfo/issues/5812
