UI Language switch implemented by propagating LocaleChanged()

notification to all the views currently active. 
Before this CL, all views were recreated instead. That was very refactoring-unsafe.

Note, this is first part of the change. It prepares overall architecture means and can be committed first.
The other part contains implementation details and is here: http://codereview.chromium.org/1551029/show
