Merge "Edits to strings to meet UI text standards. * Use contractions. * Use \u2026 instead of ... for ellipsis. * Use straight quotes (for now that's the standard). * Made the permission descriptions consistent. * Use sentence case everywhere except for proper nouns. * Notification messages need ending punctuation. * Use "touch" instead of "tap". * Use "choose" instead of "select", except when selecting text. * Use "sign into" instead of "sign in to". * Use "Do you want..." instead of "Would you like..." * Autofill has only initial cap."
