cool#9992 lok doc sign: conditionally show the add button in the sign dialog

Open the sign dialog, the Add button is hidden, even if the LOK clients
initializes the view with a working signing certificate.

SfxMedium::SignContents_Impl() knows the correct view, but by the time
the execution arrives to the DigitalSignaturesDialog ctor, this info is
lost, so we don't know what is the current view.

Fix the problem by looking up the view of the object shell at UNO
command dispatch time, and passing that around, so the signature dialog
can also access it. If the view has a signing certificate configured,
then allow signing.

The certificate chooser triggered by this button still needs fixing.
