A class of button gadget that continually sends interim om_update messages
to its target while the user holds down the button.  The button sends a
final OM_UPDATE message when the user lets  go of the button.  The imagery
for these objects is not built directly into the gadget.  Instead, a
buttongclass object uses a Boopsi image object, which it gets from its
GA_Image attribute.
