 Add the view to main window and connect search action with \a showSearchPanel

 Disconnects search action and disconnects \a showSearchPanel slot from the window.

  Makes a new view to be activated. Ensure navigation action and view label

  heading are preserved after reset.

 Builder can be shared between many instances of HsMenuView

 being in different contexts. Before using builder make sure

 it is in context matching the current HsMenuView.
