[Greasemonkey] Wrapping scripts in a self calling function

In the old days when greasemonkey actually injected a script into a userpage,
there were the potential problems of "name collisions" and "name stealing". So
that sort of wrapping was used to set up a private name space.

In the current Greasemonkey, scripts *do* run in a private namespace, so
wrapping is not needed.
