Migrate SSL certificate storage to the browser window

* Fetchers now provide the certificates before headers
* This is propagated all the way to the browser window
* When a query occurs, we retrieve it from there and fire
  the query with those stored certificates.
* The serial number is a bignum, store it as hex.
