NAME
	command - command object to do something based on a string

SYNOPSIS
	varargs int command(string str, object ob)


DESCRIPTION
	Command an object to do str and return ticks used. The second
	argument is optional and may specify an alternative object to
	this_object(). This_player() will be set to the new object
	performing the command. 

	If config.h does NOT define MUDOS_COMMAND, do_command(str) will be
	called in the new this_player(). Or else query_verb(),
	notify_fail() and commands() will be activated, and catching the
	command will require use of add_trigger/add_action.
