Reworking Security, Authentication, and Users

Team:
   I have been hard at work refactoring some core systems in order to 
accommodate a more flexible user and group model that would allow 
security.  Over the last week, I wrote a Hibernate provider for 
OpenSymphony's OSUser module and fixed the bugs in the Hibernate 
provider for PropertySets.  In addition, the authentication system has 
been abstracted (and extracted) from the jsp/servlet/struts layer.  
This will allow true authentication despite the protocol.  This system 
has been geared towards the next stage- completing the authorization 
component.
   Unfortunately, in order to accomplish this, many things were broken.  
Matt and I have agreed the best course of action is to temporarily 
break the tree.  I will begin checking in this code over the next 18 
hours.  Once complete, I will be sending an SOS for help in repairing 
the tree.
   Sorry for the inconvenience.
