Fixed serialization and status code of SOAP 1.1 exceptions

[dstenger]

Serialization of SOAP 1.1 exceptions fails:

Caused by: java.lang.UnsupportedOperationException
    at org.apache.axiom.soap.impl.llom.soap11.SOAP11Factory.createSOAPFaultValue(SOAP11Factory.java:170)
    at org.deegree.services.controller.exception.serializer.SOAPExceptionSerializer.serializeExceptionToXML(SOAPExceptionSerializer.java:143)
    at org.deegree.services.controller.exception.serializer.XMLExceptionSerializer.serializeException(XMLExceptionSerializer.java:65)
    at org.deegree.services.controller.AbstractOWS.sendException(AbstractOWS.java:447)
    ... 23 more

In addition, the OWS110 exception codes are erroneous (always 200 instead of 400/403/500).

Both issues are fixed by this pull request.
