Hi Alexandre,
this is a patch for a working SetShellWindow() implementation.
It fullfills all my test cases. Also explorer runs fine with it.
It could be a bit more clean when moving the SetWindowPos() calls from
SetShellWindow() into the Wine server. But I don't know how to do this
correctly. I tried it by calling link_window() but I had to see, this is not
enough. If you move it into the server call, you can also remove the "if
(GetShellWindow())" in SetShellWindow().
Changelog:
* Move shell window into the background and leave it there forever
* Add tests for Get/SetShellWindow() to the list of dlls/user test
