 * Announces players joining and leaving in coloured chat, together with the
 * country resolved from their IP through the geoip module (geoip_country /
 * geoip_code2). Admins and VIPs get a marker in front of their name so regulars
 * can see who just arrived. All text is plain (no external images), so it works
 * on every client including non-Steam.
