Those are the icon handlers, not the overlay handlers. Those only work
for specific file extensions (like *.sln).
We can't use them, because we'd have to register every possible file
extension to make this 'work' - which is simply not possible (that would
increase the registry over it's limits).

The same applies to all *.exe files: they each get their own icon, which
is read by a special icon handler provided by the explorer.

The shell doesn't provide such a mechanism. Sorry.
