Name: call_out - call a function with delay

Syntax:
	call_out(function fun, int delay, mixed arg)

Description:
	The call_out efun calls the function fun in the current object
	after delay seconds and with argument arg.

	Unlike call_other there can be only one argument to the function
	in call_out.

	If the function is called after the number of seconds, this_player()
	is set to the current player at the time the call_out was issued.

Return value: none

Examples:
	reset() { call_out("ring", 10, 0); }
	ring() { tell_room(environment(), "RRIIIIIINNNG!\n"); }

Note:
	call_out canNOT call functions that are declared as static!
	And via call_out you canNOT call efuns directly!
