db.php: replace with a require shim pointing to db-secrets.php outside
public_html (DB password, admin hash, CyberMail key, Square token were all
sitting in a web-reachable file, only protected by .htaccess).

index.html: update the Web Payments SDK App ID/Location ID to the new
unified Square account shared with tomtomgames.com and tomsjavajive.com.
