add permissions to control user of rest and xmlrpc API interfaces. issue2551058: Add new permissions: 'Rest Access' and 'Xmlrpc Access' to allow per-user access control to rest and xmlrpc interfaces using roles. Updated all schemas to add these new perms to all authenticated roles. Error conditions in handle_xmlrpc were not working right in manual testing. I tried to make it a little better, but I don't actually understand how the fault xmlrpc object is supposed to be used. So I may have messed something up. I'll try to ping the people who wrote the xmlrpc code to have them review.
