Notes:

TODO:
	hotkey (ctrl-shift-m?)

TODO:
	monitor explorer.exe and automatically restore when it goes away, 
	so that you don't end up with a hidden window when explorer crashes.

TODO: 
	write the install and overlay magic to work with Seamonkey. 
	Definately doable, just needs to be done.  Also TBird.

TODO: 
	give it an icon, and a button on the toolbar - the current menu item 
	thing is really more of a test.

TODO:
	ability to minimize all windows.
		-> change trayWindow::m_hwnd to a nsVoidArray
		-> change idl to get a list of docShells instead
		-> change the release magic
