Hello guys, I thought that someone might want this version so Im posting it here.
Error PrintToChat should be fixed and I have also added red/blue glow on spawn protected players. I have tested this on tf2 and its working well.
EDIT: Changed colors to orange/light blue on protected players. Fixed bug where you use "Spy!" voice command on someone and it will play sound that spy is around. It will still not work when players are colored.
EDIT2: Removed unnecessary checks. Fixed an error, being spammed in the console/logs.
EDIT3: Added some checks to ignore client 0, fixed some typos and updated some code.
