CcUserAuthenticator.authenticate() needs to catch org.apache.cxf.interceptor.Fault

[stevebillings]

ccsw.getInternalApiWrapper().getProxy().getUserApi()
.getUser(userToken);

sometimes throws org.apache.cxf.interceptor.Fault on a simple authentication failure, which is an UNchecked exception.

java.lang.Object
java.lang.Throwable
java.lang.Exception
java.lang.RuntimeException
org.apache.cxf.common.i18n.UncheckedException
org.apache.cxf.interceptor.Fault

Catch it, and return "authorization failed"
