Minor code cleanup:

* Fix possible crash in OPvPCapturePoint::AddCapturePoint due to using null pointer in log output
* Correct damage for Gore (arithmetic operator has precedence over question operator)
* Correct SQL query that WaypointManager uses to count record number
* Declare Aura *aur in OPvPWintergrasp::HandleKill only once and then evaluate value instead of declaring twice and then evaluating
