Steps:
1. Load Home Page Reader and Mozilla or Firefox
2. Alt+Tab between them quickly

What happens:
Mozilla/Firefox crashes
I was able to reproduce this in the debugger. NotifyWinEvent is crashing becasue
we're reporting a focus event for our child, but in HPR's window.

We used to insist that the window we fire a MSAA focus event for was the same
window that Windows reported has focus. However, this was only added for
Window-Eyes and my testing shows that with recent versions of Window-Eyes this
is no longer necessary. By removing this code, we no longer accidentally fire a
focus event for a window in some other application, as the user hits Alt+Tab
(The Alt in Alt+tab very briefly activates the main menu bar which causes a
focus event).
