Now all focusable controls realize focus method and handle focus/blur events. Now as far as I know xul and xhtml controls don't fire DOMFocusIn/DOMFocusOut events but specs is asked for http://www.w3.org/TR/2005/PER-xforms-20051006/index-all.html#evt-DOMFocusIn.
We need to create base binding which support focus method and DOMFocusIn/DOMFocusOut events firing.

Reproducible: Always

The idea of code dublicating lessing is fine. But I don't see a good way how can I implement it. I guess the focusable base binding should have:
1) method focus()
2) focus/blur event handlers.
But problem is that focus() method is property of interface binding, focus/blur handlers are properties of context specific binding (binding for xul or xhtml). It means if I will have focusable interface binding than I should be move focus/blur handlers into interface binding. I don't like it a much.

Does is block anything? Marking it an "enhancement" as I guess it is not.
