Added a command option "setlabel box" to modify the attachment box

of a label from the command line.  Also fixed a long-standing
irritation that "setlabel" would change the properties of a label
in the edit cell but not in the selection itself, which would
cause the label to be drawn both with the original properties
in the selection and the new properties in the edit cell.  Now
both views will track the same changes.
