Neighborhood Stories Expanded

This game update added code to ensure incompatible sims don't end up together through neighborhood stories; however, it doesn't take into account whether sims are still exploring. Most sims default to having neither male nor female gender preference selected with exploration on. That configuration would make them ineligible for romantic neighborhood stories with the way the new code was added. I changed that so sims can be chosen for stories if they're exploring, even if they don't have any gender selected.
