NAME
	command - execute a command in a living object

SYNOPSIS
	int command(string cmd)

DESCRIPTION
	With this function an object can command itself to perform an action
	that previously has been added with add_action. The given string
	"cmd" should be on the same format as if it had been given from the
	command line.

	command() returns the number eval-cycles that was used to perform
	the command, or 0 if it proved impossble due to eval-cost.

	When commanding a player to do anything, the command must be
	prefixed with a "$" to prevent the quicktyper from being invoked.
	Use command("$smile"); to make it impossible to have smile aliased
	to another command.
