Add glade_command_set_sensitive() and port a bit of the GTK+ plugin code to itcommand-set-sensitive

The aim of this is to let all changes to the sensitivity of properties through
the command system so that the code in the "gbinding" branch can cleanly react
to the source or target of a property binding becoming insensitive (e.g. by
undoably removing the binding).
