* If BuildApplet.py is used as an applet it starts with a version of

sys.exutable that isn't usuable on an #!-line. That results in generated
  applets that don't actually work. Work around this problem by resetting
  sys.executable.
* argvemulator.py didn't work on intel macs. This patch fixes this
  (bug #1491468)
