KDirOperator: Make "newest first" the default kind of date sorting
When sorting by date, "newest first" is more useful in the context of a file dialog where you're more likely to want to interact with newer files rather than older ones.
To implement this, KDirOperator now inverts the sort order it's told to apply when sorting by date. It has to be done this way because the "reversed sorting" setting is stored globally, not per sort method.

I'm not as sure that the same logic makes sense in Dolphin, where you're more likely to want to "tell a story" with the sort ordering reflecting some kind of long-term organizational strategy. But for transient file open/save dialogs, I don't think that's a concern, because you probably do want to see more recently-used files when opening or saving.
