Lfun:	load_chat - make a monster talk

Synopsis:
	void load_chat(int chance, string *chats)

Description:
	The load_chat call tells a monster to chat if a player is present
	and if there is no fight. The first argument is the chat chance of
	each heart beat (2 secons) and is an integer between 0 (no chat) and 
	100 (chat every heart beat).

	The chats argument is an array of chat strings, from which one is
	randomly selected if the monster wants to make a chat.

Return value:
	none

Examples:
	load_chat(2, ({
		"Harry says: What are you waiting for?\n", 
		"Harry says: Hello there!\n",
		"Harry says: I don't like winter.\n",
		"Harry says: I don't like snow.\n",
		"Harry says: I don't like rain.\n",
		"Harry says: Who are you?\n",
		"Harry says: Why do you look like that?\n",
		"Harry says: What are you doing here?\n",
		"Harry says: Nice weather, isn't it?\n",
		"Harry smiles.\n"
	}) );
