Merge "Settings strings cleanup per standards. Bugs: 5165745, 5163232, 5162668, 5162667, 5162328 Implementation of language and spelling changes requested by Design such as WiFi. Also removed some dialog titles per Design. Will file separate bug to have the titles removed properly; for now I just made the string empty."
