Since we don't post any notifications right now, is this necessary?

Done.

We are not handling any of these intents in the activity to process the URL and
start a navigation. I would suggest add a subset of the filters in this patch,
and add the intent handling logic for them to the BlimpRendererActivity.
Take a look at ChromeLauncherActivity and IntentHandler.
