Fix Bug 296970 - split view wrong behavior with search tab

Review Request #112534 - Created Sept. 5, 2013 and submitted

Emmanuel Pescosta
Implemented setActive(bool active), isActive() and activated() signal
for DolphinSearchBox - similar to the KUrlNavigator implementation.

The search box sends the activated() signal when one of the child widgets
gets the focus.
Works for me.

1. Enable Split View
2. Start search in one of the two views
3. Activate the other view and wait for search finished
4. Change the search text and notice that the active view is now the view with search enabled
5. Go back to the other view immediately after you have finished the search text change
6. Only the view with search enabled should show the search results
