* gtk/gtkbutton.c: set RECEIVES_DEFAULT on init, and a
button press on the widget doesn't grab default anymore
* gtk/gtkcheckbutton.c,gtk/gtkoptionmenu.c,gtk/gtkradiobutton.c:
unset RECEIVES_DEFAULT on init
* gtk/gtkwidget.[ch]: add a RECEIVES_DEFAULT flag to widget
flags
* gtk/gtkwindow.c,gtk/gtkplug.c: on pressing <enter>, activate
the focused widget if it is a RECEIVES_DEFAULT widget,
no matter what the current default_widget is
* gtk/gtkwindow.c: on focus change, migrate the HAS_DEFAULT
flag to CAN_DEFAULT widgets if they RECEIVE_DEFAULT as well
or migrate it back to the default_widget if the focus widget
doesn't "RECEIVE_DEFAULT"
