Series SOLR config parameters are missing

The are currently 5 SOLR indexes in Matterhorn (workflow, scheduler, series, search and episode). All of them accept two configuration properties to allow the administrators to customize the location where the index files are stored, or to use an external SOLR server instead.

However, in config.properties, only the following properties are included:

org.opencastproject.episode.solr.dir
org.opencastproject.episode.solr.url
org.opencastproject.search.solr.dir
org.opencastproject.search.solr.url
org.opencastproject.workflow.solr.dir
org.opencastproject.episode.solr.url
org.opencastproject.scheduler.solr.dir
org.opencastproject.series.solr.dir

And the following properties, despite being perfectly functional, are missing:

org.opencastproject.scheduler.solr.url
org.opencastproject.series.solr.url

These three last properties should be included in the file (commented by default, as the ones that are already present, to remind the configurators that they can externalize those two indexes too).
