[K12OSN] Lock down proxy settings and home page

[Brian Chivers]

Sorry might be too late on this one but thought I'd added this anyway :-)

We use CCK Wizard (https://addons.mozilla.org/en-US/firefox/addon/2553)

it allows you to create a plugin that sets loads of things like proxy & 
hoepage & then install it as a global plugin so it's installed for all 
users.
