Fix crash when ending a chat line with ¬ about avara

[assertivist]

This is fixed but that code still lives on. I think it is needed to divide lines up for the chat tab.

I also don't really like the stuff that goes all the way back out to GUI code to make chat lines, but actually thats how the original did it too:

Avara/src/game/CPlayerManager.cpp

Lines 609 to 680 in 30ded35

	void CPlayerManagerImpl::FlushMessageText(
	Boolean forceAll)
	{
	Str255 fullLine;
	short maxLen;
	short baseLen;
	GrafPtr savedPort;
	TextSettings savedTexs;
	OSErr err;
	GetPort(&savedPort);
	SetPort(theRoster->itsWindow);
	GetSetTextSettings(&savedTexs, geneva, 0, 9, srcOr);
	do
	{
	BlockMoveData(playerName, fullLine, playerName[0] + 1);
	#if 0
	while(fullLine[0] && fullLine[fullLine[0]] == 32)
	{ fullLine[0]--;
	}
	#endif
	TruncString(kChatMessageWidth/3, fullLine, smTruncEnd);
	fullLine[++fullLine[0]] = ':';
	fullLine[++fullLine[0]] = ' ';
	baseLen = fullLine[0];
	maxLen = lineBuffer[0];
	if(maxLen + baseLen > 250)
	{ maxLen = 250 - baseLen;
	}
	BlockMoveData(lineBuffer+1, fullLine + 1 + baseLen, maxLen);
	fullLine[0] += maxLen;
	#if 1
	err = WordWrapString(fullLine);
	#else
	err = TruncString(kChatMessageWidth, fullLine, smTruncEnd);
	#endif
	if(err == 1 || forceAll)
	{ short outLen;
	if(err == 1)
	{ outLen = fullLine[0] - baseLen - 1;
	}
	else
	{ outLen = maxLen;
	}
	if(outLen != 0) theRoster->NewChatLine(fullLine);
	BlockMoveData(lineBuffer + outLen + 1, lineBuffer + 1, lineBuffer[0] - outLen);
	lineBuffer[0] -= outLen;
	if(err == 0) forceAll = false;
	}
	} while(err == 1 || forceAll);
	isLocalPlayer = (theNetManager->itsCommManager->myId == slot);
	if(isLocalPlayer)
	{ theRoster->SetChatLine(fullLine);
	}
	RestoreTextSettings(&savedTexs);
	SetPort(savedPort);
	}

additionally, i was gonna say something about making it match by renaming the function to FlushMessage but then i realized that I ALSO ignored an old function RosterKeyPress when i was making special characters show up in the roster chat! so i have no room to talk! And i'm closing this!
