(The control panel now contains the relevant state of a running Walnut -- ie., the message set buttons contain the version numbers of all of the currently displayed message sets and the version number of the message set domain)

(This was substantially reworked and simplified -- it now is the interface that handles the internal details of the Walnut Window, ie., how messages are reported and the display of message set buttons.)
