Subject: [PATCH] Statistik: Login-Tracking auf pro-User-Deduplizierung
 umstellen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

main_contact_id wird jetzt mitgespeichert + UNIQUE (login_date, main_contact_id).
Damit zählt ein User der sich mehrfach ein-/ausloggt trotzdem nur einmal pro Tag.
Im Chart bleibt nur die anonyme Tagessumme sichtbar.

ALTER TABLE stat_login_daily
  ADD COLUMN main_contact_id INT NOT NULL DEFAULT 0 AFTER login_date,
  ADD UNIQUE KEY uq_user_day (login_date, main_contact_id);
