Added support for running massive statistics selects on a SQL slave server if configured in config.inc.php. Inserts/updates still go to master.
- requires setup of APP_SQL_SLAVE_* copies of the APP_SQL_* config vars in the config.inc.php file to enable this.

Update SWF file uploader
*REQUIRES SOLR schema.xml update based on solr-31_schema.xml*
- Added sek_lookup_function search key values to solr so they don't have to be looked up after a page load to improve performance (still to be disabled after this)
- Added sherpa/romeo data, admin internal notes to solr
- Changed the cleaning of pdf content to happen during cache time, rather than reading from cache - requires a single sql UPDATE clean once off of existing data though - to be added to an SQL upgrade..
- reformatted class.fulltext_index_solr_csv.php indentation via phpstorm autoformat
*still to do: add ERA 2010/2012 matched journal and conference lookups*
