Added a killedby column to character_corpses, so we can track how the player was killed. Values are:

0 - Other (Pain and suffering)
1 - NPC killed them
2 - Environment (Drowning, falling, burning, freezing)
3 - Duel
4 - Non-duel PVP

Implemented a 10 minute rez timer for corpses left due to losing a duel.

Fixed an issue where the rez status of a corpse would not update in the DB following the rez timer expiring.

Adding some missing code from EQEmu for tell queues (completely untested by me)
