Add ScriptController::updateSecurityOrigin

[Adam Barth]

We should call a method on ScriptController when we update a document's securityOrigin.  V8 uses this method to update the security context it uses in its fast-path security check.  Currently, the JavaScriptCore bindings don't have use for this method, but it might in the future.

Patch forthcoming.

For those keeping score at home, this method corresponds to / replaces SecriptController::setDomain in http://src.chromium.org/viewvc/chrome/trunk/src/webkit/port/bindings/v8/ScriptController.h?view=markup

The indentation looks odd here.

And here.

FYI: indentation looks to be off by one space.

Thanks.  I think I fixed this before landing.
