get_instance() in pre_controller hook?

[eluser]slowgary[/eluser]
I actually solved (most of) the problem without a hook, since it needed to happen early on in my application, not in any of the post hooks.

I'm already using a BaseController class in MY_Controller, so I just tossed a few preg_replaces in the constructor of BaseController, which strip anything starting with a question mark from $this->uri->uri_string and the last segment of both $this->uri->segments and $this->uri->rsegments.

Now the only problem that remains is query strings on the root domain, e.g. www.mydomain.com?utm_campaign=yadayada.

Since it has nothing to do with the URI string at that point, but still confuses CI, it breaks the app. When I figure out how to overcome this I'll post a reply for the next guy.
