. Rhino JavaScript integration:

- APIs for testing of Permissions and checking that an Aspect exists on a node

. Added new command processor to config for Command Servlet
   - new command processor to allow execution of Alfresco JavaScript files via URLs
   - Wiki docs: http://wiki.alfresco.com/wiki/URL_Addressability#Script_Command_Processor

. Fixed issue where a deleted/missing NodeRef on the end of a Link object would cause errors in the web-client
   - Still needs cleanup/change to assoc mechanism as per AWC-647
