Update ClientSettings.php and WebsiteSettings.php

~ Add extra checks to Alphaland\Client\ClientSettingsApplications::FetchCombinedApplicationDependencies() to:
  1. Determine if the application dependency actually exists
  2. Determine if the application dependency has a dependency to it's
     super dependant

~ Make the Alphaland\Client\ClientSettingsKind an abstract class

~ Add Alphaland\Web\WebsiteSettings::GetOrCreateSetting() to website
settings in case we want to write a setting if it truly doesn't exist
