soap_fault_spec.rb: Added some specs saying that the SOAPFault class should be able to handle it if the nori parser is configured to convert tag names to hash keys in a non-default way.
Merge branch 'new_soap_fault_spec' of git://github.com/DavidEGrayson/savon into DavidEGrayson-new_soap_fault_spec
