Dashboard index page revised

The dashboard index page (which lists all dashboards and provides controls for them) has been drastically revised and improved to support new features.  You can now select multiple dashboards and copy, delete, share them as well as rename, set a default dashboard and change your dashboard order.  You can also preview your dashboards before loading them.  You can visit the dashboard index page by clicking the ‘manage dashboards’ link from your home page, or the home page icon from any dashboard page.  Additionally, under your user settings, you can opt to make your dashboard tab link directly to the dashboard index page (vs linking to your default dashboard).
