When a widget is being modified, move focus to that control and change page title

[Slava Akhmechet]

If a page has a number of widgets and a particular action causes some widget to change, that widget should receive focus (via JS for ajax, and via anchor otherwise) to ease the pain for users with screenreaders. Also, page title should change to a phrase that describes the current state of the widget in question.

We need to think of what to do when multiple widgets change on the page. Perhaps the most likely solution is not to set focus/title in such cases, or set a title that describes state of all widgets.
