Subject: [PATCH] Final step in making applets first-class citizens: if the
 applet wants argv emulation (i.e. if the end user drops files and folders on
 the applets these will show up in sys.argv) BuildApplet will add the required
 code to the applet bundle, in __rawmain__.pyc.

This code is compiled from appletrawmain.py, it creates sys.argv, cleans
up most of the mess and executes either __main__.py or __main__.pyc.
