refactor(ng:view) Make $route scope agnostic, add $contentLoaded event

Problems:

- controller was instantiated immediately on $afterRouteChange (even if no content), that's
different compare to ng:controller, which instantiates controllers after compiling
- route listened on current scope ($afterRouteChange), so if you were listening on $rootScope
($afterRouteChange), you get called first and current.scope === undefined, which is flaky
- route handles scope destroying, but scope is created by ng:view
- route fires after/before route change even if there is no route (when no otherwise specified)

Solution:

- route has no idea about scope, whole scope business moved to ng:view (creating/destroying)
- scope is created (and controller instantiated) AFTER compiling the content
- that means on $afterRouteChange - there is no scope yet (current.scope === undefined)
- added $contentLoaded event fired by ng:view, after linking the content
