group blob list by date

[adamfoneil]

In the list view showing recent blob names, group them by date for easier selection. Having a date grouping helps jog your memory about what the images are. Since the names are meaningless, having a date divider helps orient you in the image list.

ListView Groups do not seem to work. I can find others reporting this symptom

One suggestion I see says to use Application.EnableVisualStyles() but I'm already doing that.

And yes I have ShowGroups = true

I considered Component Owl's but I don't think it's cost-justified.

I think the only practical alternative is to use a TreeView + ListView combo, where the TreeView provides the grouping. But I don't like what this will do to the layout overall.
