Fixed a nil error when attempting to remove a nonexistant body

Fixed the body improperly being shown as confirmed dead when df_identifybody is 0 and fixed the df_traitoronly convar

Uses a hook now instead of overriding a gamemode function

Fixed bad use of convar

Remove a bit of code that should not have been there

Fixed death not showing up on scoreboard, added 2 more convars, and cleaned up the code a bit

Zerf cleaned up the code a bit

It now shows you as "Confirmed Dead" on the scoreboard when you drop the body
