	* ContainerControl.cs (set_ActiveControl): rework this a bit (and
	add some nice ascii art pictures and explanation of the process).
	(GetMostDeeplyNestedActiveControl): new utility function we need
	because our ActiveControl can refer to a child container with its
	own ActiveControl.

	* Form.cs (OnActivated): remove the call to SelectActiveControl
	from here, since you can override this method and not chain up,
	and winforms still sets the active control.
	(OnCreateControl): also remove the unnecessary SelectActiveControl
	call from here.
	(WndProc): it's actually called from the WM_ACTIVATE block, just
	before calling OnActivated.

	* Control.cs (Select (Control)): move the call to XplatUI.SetFocus
	inside the else.  the ActiveControl setter will end up setting
	focus on @control.  This keeps us from setting it again (and
	generating an extra LostFocus/GotFocus pair).
	(Select (bool, bool)): reindent.
