Support for InclusiveNamespaces for method = enveloped

[mdonnie17]

For method = enveloped, current XMLSigner.sign() does not add InclusiveNamespaces. It will then fail when calling XMLVerifier.verify()

current: ds:Transforms <ds:Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/> <ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> </ds:Transforms>

Proposed: ds:Transforms <ds:Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/> <ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"> <ec:InclusiveNamespaces PrefixList="xs" xmlns:ec="http://www.w3.org/2001/10/xml-exc-c14n#"/> </ds:Transform> </ds:Transforms>
