Death Messages V2 for stock PC/CE maps for SAPP

-- Death Messages V2 for stock PC/CE maps for SAPP
-- by H® Shaft

-- V2 Changelog: added melee damage variable, and fixed/edited backtap

-- Script will show how players were killed/died: Normal death messages are blocked (no chat spam), examples :
-- "H® Shaft was blasted by sehé°°'s banshee plasma cannon."
-- "H® Shaft was blown-up by sehé°°'s's frag grenade."
-- "H® Shaft was shot by Btcc22's sniper rifle."
-- "H® Shaft was melee'd by Btcc22!"
-- Will tell Killer and Victim if they were killed by Headshot (pistol and sniper only) "BOOM! You were headshot! by H® Shaft"
-- Will show when a player died by: Falling, by Vehicle or Team Change, will not show if killed by the server
-- Will show player their combination kills, and announce to everyone your sprees: "H® Shaft is on a Killing Spree!"
-- Allows server admins to turn fall damage on/off PER map: see LoadDefaults() true, fall damage is on, false it is off (line 416)

-- specify the amount of damage done by melee or backtap: 0 = disable melee kill, 1 = normal, 2 = double, 3 = triple, 4 = quadruple
melee_damage = 1
