Have the RenderThread initialize a PhishingClassifier when it receives a

ViewMsg_SetPhishingModel message from the browser, and run it after pages
load in the renderer.  The phishing classifier will only run on new
navigations where the toplevel URL has changed.  Since we need to keep the page text around in memory in the case where the model is not yet set when a page loads, this is also conditional on a command-line flag.

The next steps will be to send the SetPhishingModel IPC from the browser, finish implementing the DetectedPhishingSite IPC, and ping to confirm the phishy verdict.
