Merge "General string scrub to bring to standards, (punctuation, capitalization, wording, etc.) I need reviewers to advise on use of periods: No period is used for setting summaries, dialog box titles, column headings. Periods are used for message text, status bar messages, full-screen messages ("No favorites.") For some of the strings I can't tell the exact context.
