Sorry, I meant, store this as a scoped_refptr<PrefStore>. But that may not work
if you need to call Init() in client code.

[jonross, 2016/11/19 00:35:36]

Ah, yeah.

I had planned for client code to call Init. That way each component can register
on demand.

The chrome side has a few monolithic spots where it registers all prefs. We
could do something similar, however I am hesitant as that has lead to issues
with bringing up unit tests.
