XQuartz: Make a call to activateIgnoringOtherApps in our NSApplicationActivatedEventType handler

In addition, this change will not call into the X11 activation unless an X11
window was active when we deactivated.  We can't rely on the event and current
key windows because the key window will be nil until activated, and the event
will only reference the window if the window was clicked (whereas it will be
nil if we activated via dock or cmd-tab).
