Tweaked -descriptionWithOptions:

* Fixed extra comma in the output of -[NSSet descriptionWithOptions:]

* Just use -description to print collection values with -descriptionWithOptions:
in NSSet, NSArray and NSDictionary

* Use -description as the object short description selector rather than -stringValue
