+-- One row per kill, bomb plant and bomb defuse, written as it happens (0.2.0+). Nothing during
+-- warmup. Kills leave out suicides and team kills.
+-- kind: 1 kill, 2 bomb planted, 3 bomb defused. steamid64 is who did it: the killer, planter or
+-- defuser. The kill-only columns are NULL for plants and defuses, and site is NULL for kills.
+-- victim_steamid64 is NULL when the victim was a bot (victim_bot 1).
