NEW: Add a clan tag function like csgo's "CS_SetClientClanTag"

[ZZHLMY]

Hello, sorry to my poor English, I setup team tag at player's name when player join team, if I want to remove their team tag when player change to team spectator, name tag wouldn't change untill player next respawn. If player respawn it would caused player have two team tag.

I hope amxmodx group can make a function like csgo's "CS_SetClientClanTag".

Thanks.
