display non-recursive size/counts

[lgarrison]

Because we only display recursive sizes/counts, it can be hard to tell if most of the usage is in the current dir or the subdirs. If there are only a few files/subdirs, it's not hard to add up the subdir sizes by eye and compare that to the recursive size, but we may want a better user experience for this. Displaying the non-recursive size and counts in the cwd would help with this.

The main question is where/how to display this info on the UI that makes it clear that the size is *non*-recursive. All the other sizes are presently recursive.
