Images can how be added to blocks (r440).  Use:
  this.appendTitle(new Blockly.FieldImage('http://example.com/cat.gif', 12, 12));
The block factory has been updated with the ability to add images.  The text 
block has been modified to display a couple of oversized quotes as an example 
of the use of images.

Still todo:
* Modify block rendering to expand vertically to fit the image (it does expand 
horizontally).
* Add wiki documentation.

Blocks now resize to accommodate large images.  Documentation has been updated. 
 Enjoy!
