Subject: Implement deleting dashboard blocks.

* Refactor blocks so that they have a separate id vs css_id.  This way
  we can have a unique identifier for each visual block.

* Store blocks with a random id as their unique identifier

* Add Admin_Dashboard::remove_block() and modify
  themes/admin_default/views/block.html.php to call it when you click the
  remove box.
