Checkmk Werk 14336: Fix edit of dashboards without header

ID: 14336 Title: Fix edit of dashboards without header Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 If a dashboard was configured with option "Show the header of the dashboard with the configured title" disabled, the "Edit dashboard" link only showed the dashboard. The option to edit the dashboard is now disabled for such dashboards and will show a hint, that the header must be enabled to use the edit mode.
