Bug 468497: Inform the accessibility FocusManager when a XUL tree's view changes. r=MarcoZ

Browse Source 
Without this, accessibility clients don't get notified about the newly focused item.
For example, this meant that nothing was reported by screen readers when switching tabs in Thunderbird with control+tab.
