Subject: Rewrite iteration through applet names to save a few bytes

function                                             old     new   delta
run_applet_and_exit                                  758     755      -3
------------------------------------------------------------------------------
(add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3)               Total: -3 bytes

In standalone shell mode the saving increases to 17 bytes.
