Subject: [PATCH] ui: reject extended clipboard message if not activated

The extended clipboard message protocol requires that the client
|
|
activate the extension by requesting a psuedo encoding. If this
|
|
is not done, then any extended clipboard messages from the client
|
|
should be considered invalid and the client dropped.
