[webkit-dev] Important change for ports regarding FocusController

[David Hyatt]

In order to get focus memory for tabs working properly, we need a  
notion of whether or not the underlying Page is focused.  We need this  
since Web pages should be able to shift around programmatic focus in  
background tabs and have the new focused frame and focused node be  
remembered if you switch back to that tab.

Our current code was relying only on the window being active plus the  
frame being focused to decide that it should draw focus rings and  
blink carets.  However this isn't good enough in the case described  
above.

I have just added a new boolean to FocusController that indicates  
whether or not the Page is focused.  The Mac and Windows ports have  
been patched to update the Page focused state properly (I hope).

Other ports will need to call page->focusController()- 
 >setFocused(true) or setFocused(false) now in order for everything to  
work properly.
