This change fixes a bug with revocation message decoding that
would cause client and server failures if the revocation message
was included in a Revoke operation call. With this fix, the client
can now send a revocation message with a Revoke request and the
revocation will occur as expected.
A ProxyKmipClient demo script for the Revoke operation has been
included to help test Revoke functionality.
Finally, an argument ordering bug with the original KMIPProxy demo
Revoke script has also been fixed.
Fixes#546
