function sarnia_entity_load in Sarnia 7

Implements hook_entity_load().

Add Solr properties to Search API Index entities' fields if they're managed by Sarnia.

SearchApiIndex::getFields() returns only fields that are in both $index->options['fields'] and the EntityAPI properties. This means that we have to inject the Solr properties both in hook_entity_load() and in hook_entity_property_info().
