SDK Updater: SettingsController that handles the settings.

Browse Source 
There is not any longer any logic in the SettingsPage,
it is handled now by a "SettingsControllers" which is
available via UpdaterData. The page only takes care of
notifying the controller via a callback when settings
have changed in the UI.
