Antony, could you take a look?

This makes them external component apps, which means they 

-can't be uninstalled
-won't show up in chrome://extensions

Are you sure that's what we want, as opposed to just making them regular default
apps?

Good call. Here's (I think) a better approach, as we discussed.

As far as I can tell, it looks safe to change the default apps provider to allow
external_update_url values.
