Add Advanced Dashboard Implementations

[FrederickChan]

Currently Administration Dashboard is being supplied with Admin Themes. That is, it is supplied as custom code by the Theme itself.

The Admin Dashboard should have its own core MVT capabilities, and allow all future admin themes to be able to be customized at theme level.

• Data should be supplied by a class get function.

• Custom Control can be implemented by the Admin Theme itself

• Add support for Hooks to be implemented for additional custom dashboards capabilities. For a multi-capable system CMS, dashboards provide good analytics and insights to the performance/index indicator of the site. This will be a neat feature to have and provides justifications for people to upgrade to the latest version.
