    Implemented discussion from bug 2547:
    * Block authors no longer need to set $this->content_type
    * If you want to make a "list" block, just derive from block_list
      instead of block_base
    * All switch() statements gone from library code
    * Overloaded method is_empty() added to block classes for convenience
