Currently, when clicking the tray icon, the following happens:

        private void OnTrayClick(object o, EventArgs args)
        {
            WindowPlayer.Visible = !WindowPlayer.Visible;
            ResizeMoveWindow();
        }

This behavior is fine, but could use some improvements:

 * If banshee is visible, but not on the currently visible desktop, don't hide it, instead show it on the currently visible desktop.
 * If banshee is minimized, don't hide, yet unminimize.
 * If banshee is hidden behind other windows, don't hide, but bring it to the front.

The tray icon behavior would then be the expected "If I see banshee and I click on it, hide it! If I don't see banshee and I click on it, show it!".

Currently the only application that does this right (as far as I know) is gaim, the code for this is here: http://cvs.sourceforge.net/viewcvs.py/gaim/gaim/plugins/docklet/

Will look into this someday in the future (when time permits it), marking it as a gnome-love task for now. If someone is willing to look into this, please do!
