Bug 1053610 - Perist places storage in local idb. r=kgrandon

Yeh I wanted to change a few things here, but didnt want to increase this patch, I think we should just remove .filter and have the persistence engine deal with that, didnt want to put any filters on the places though, it doesnt cost a lot and is more flexible (we may want frecency of app:// urls at some point)
