Safari extension that preventDefault()s any beforeload event

Overview:
HTML <applet> elements do not fire a 'beforeload' event before the Java resource is fetched and executed.

Steps to reproduce:
1. Install the attached extension. It only has the following injected script:

document.addEventListener('beforeload', function(event) {event.preventDefault();}, true);

2. Navigate to any page with an <applet> tag, such as

http://java.sun.com/applets/jdk/1.4/demo/applets/ArcTest/example1.html

Actual result:
The Java applet loads and runs normally.

Desirable result:
The Java plugin should not run at all.

Additional information:
This would allow a Safari extension to conditionally prevent
the Java plugin from running, as is already possible with all other plugins.
