Fixes #3084

The message will appear on mob creation and also if the player check their notes.

Known thing I can't do anything about: There's no good way to selectively delete memories which may or may not exist on a mob. Someone who gets turned into a lot of ventcrawling mobs (a ling who likes lesser forming, a player slime reproducing) will continue to accrue a new message with each new incarnation. Considering we log multiple times of death in the same fashion I'm calling non-issue.
