Protege 2.1 Beta update (build 199)

There's a new beta build available on our Web site: 
http://protege.stanford.edu/download/prerelease/index.html

Changes
-------------
1. Fixed a problem which caused "java packages" classes not to load from a 
plug-in directory.

2. Fixed behavior of subslots so that the correct attributes are inherited 
from their superslots.

3. Modified "create inverse slot" code to automatically create an inverse 
slot that has the correct allowed-classes, domain, and superslots.

4. Modified the "create subslot" code to automatically create the 
appropriate inverse slots for subslots of slots with inverses.

5. Made some hacks so that subslots of :DIRECT-TEMPLATE-SLOTS behave more 
"correctly".

6. Fixed a number of API methods that didn't work when accessing a project 
on the server.

7. Journaling now works.

8. The CLIPS back-end used to create and then delete a class as a side 
effect of 	doing a save. It no longer does so. This change required some 
rather extensive modifications to the CLIPS back-end. Users of the CLIPS 
(default) back-end should backup their projects before upgrading.
