TODO:
1. In DoStaticShellExtensions, check for "Explore" and "Open" verbs, and for BrowserFlags or
ExplorerFlags under those entries. These flags indicate if we should browse to the new item
instead of attempting to open it.
2. The code in NotifyShellViewWindow to deliver commands to the view is broken. It is an excellent
example of the wrong way to do it.
