        * Makefile.am: add widgets directory; move calendar idl stuff to calendar directory; stop make a single shared lib for whole a11y stuff.
        * ea-factory.h: make factory macros available to GOBJECT
        * calendar/Makefile.am: add calendar idl stuff
        * calendar/ea-cal-view-event.c: add atkcomponent interface.
        * calendar/ea-gnome-calendar.c (ea_gcal_switch_view_cb): add details for "children_changed".
        * new widgets directory for widgets a11y stuff, new files are:
                widgets/Makefile.am, widgets/ea-calendar-item.c, widgets/ea-calendar-item.h, widgets/ea-widgets.c, widgets/ea-widgets.h
