Changes
-------------
1. Fixed a longstanding problem which sometimes caused "Operation on closed 
kb" stack traces after closing a project.

2. Searching in class trees now works in situations with recursive 
inheritance. Previously it resulted in "stack overflow" messages.

3. An attempt to create a database project by overwriting an existing 
database table now results in a warning dialog.

4. Fixed a problem which sometimes caused save failures on new Clips and 
RDF projects.

5. Added code to the graph widget that prevents anonymous classes from 
being displayed in the palette (applicable to Protege OWL projects).

6. Added a getImage() method to the graph widget that allows you to get the 
contents of the graph widget as an image.  Also posted example code on the 
Wiki that demonstrates how to use the method and save the resulting image 
object to a file:
