Subject: [PATCH] Handle $stop and $finish at the interactive prompt.

This patch adds interactive support for $stop and $finish.
$stop displays a message that the simulator is already stopped.
$finish acts exactly like (calls) the interactive "finish"
command. Having $stop do nothing and $finish not finish until
you exit interactive mode is not very intuitive.
