android: Persist settings across configuration changes
Mostly things get refactored here to remove previous assumptions made about how the activity/fragment lifecycles would operate. The important change for persistence is removing the assumption that the user will be at the first settings fragment on recreation when deciding whether or not to reload settings. Now we check a flag in Settings to know if we loaded the settings within this lifecycle.
