* moved initial model events bindings for widget from browserInit to constructor (need it to change logic of browserInit later)
* polished a little Context's special init mode behaviour
changed way of rebuilding the page while browser-side page switching: new widgets and inline-blocks of widgets are firstly initialized with behaviours in "ephemeral" nodes and only after full initialization are added to the DOM three. Pros:
* should be faster
* users will never see uninitialized widget that is not yet reacting to their actions
* CSS-files loading is now guaranteed before showing the widget.
