defacer 3ef642d96a 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
