app_server can mark windows as minimized when they are showing

[leavengood]

Once they are in this state they cannot be actually minimized (hidden) again.

Steps to reproduce:

1. Open a window, such a home in Tracker.
2. Open the Workspaces applet.
3. While hold CTRL and SHIFT, click the window in Workspaces. This will hide it. Don't move the mouse!
4. While keeping the mouse in the same location, hold CTRL and click again. This will bring the window to the front, essentially un-minimizing it.

You now have a window that cannot be minimized again. Not by double clicking the title, not by using the deskbar, nor by CTRL-SHIFT-clicking again in Workspaces.

I think the issue is the minimized flag is not unset when the window is brought to the front.

And obviously it is a bug in the WorkspacesView in the app_server to bring minimized windows to the front like that. But the app_server should not let windows get in this state.

Turns out this is specific to how Workspaces was showing minimized windows and is fixed because of hrev44512.
