Activate "allow scripts globally" in prefs.js

Hi there,

Thanks for the great add-on.
I have installed Debian Wheezy (Firefox 10-ESR) on the desktop computers of a company with non tech-savvy users. I would like to block Java while allowing Javascript globally. I know how that can be achieved with the GUI, but I will have to deploy it to a lot of PCs with existing Firefox profiles. Adding something like to the system-wide equivalent of prefs.js (/etc/iceweasel/pref/iceweasel.js on Debian)

lockPref("noscript.forbidJava", true);
lockPref("noscript.global", true);

will block Java also on whitelisted sites, but is there an option to do the same thing for "allow scripts globally"?
I know about the dangers of this, but I must make sure the employees get at least some degree of protection without having to whitelist anything themselves.

Thanks a lot!
