Simplified the logic updating the TabPages.

Browse Source 
- The new logic of adding/removing tabs in the ChangeToNewTabs method also fixes
  tab-title flickering when we move from the Home node to a disconnected host.
- Renamed enum members Tab.Overview to Tab.Search and Tab.Settings to Tab.General
  since the pages mapped to them are TabPageSearch and TabPageGeneral respectively.
- Do not call directly UpdateToolbarsCore but rather UpdateToolbars since the
  latter takes account of the queued requested updates.
