Add histograms to track synced pref changes.
Certain prefs will now elicit stat tracking
whenever they are changed locally and pushed to
sync, or when changes from sync server are pulled
down to update the local pref store.
New histogram names take the form:
Settings.$prefname.Changed{FromSync,Local}
The logged value is the new pref value imposed by
the change.
