Chat system improvements

Overall description of the new feature:
teamChat - messages from opponents are written only in console! No 
beeps/showing on the screen.
(Current one are not working when your teammate is dead (his team is 
TEAM(BLUE/RED)_SPEC))
SpecsChat - messages from spectators are written only in console! No 
beeps/showing on the screen. But every message can be read in console 
later.
ChatBeep - on/of sound when message received.
Current variable dead_talk (not sure about name) doesn't stores chat logs 
anywhere. Maybe it is possible to store them somewhere.. To be able to read 
them after round/match ended. OK about other team messages - they are 
private, but NOK about spectators messages. Also I insist on renaming the 
current variable. Its name is not obvious. deadTalk or something similar 
would be OK.

Variables to control the new feature:
I'm bot sure about names.. And not sure that it is cgame part and not 
binary.
(the value is default one)
cg_teamChatOnly 0
cg_specsChat 1
cg_ChatBeep 1

Which game parts are involved:
binary?
N/A
game?
N/A
cgame?
