* gui/calendar-component.c (create_new_event):
* gui/e-calendar-view.c: (e_calendar_view_edit_appointment):
* gui/comp-editor-factory.c (edit_existing),
* (edit_new):
* gui/dialogs/event-editor.c
* (event_editor_edit_comp),
 (event_editor_new): updated the calls to event_editor_new
with additional argument.
* gui/dialogs/event-editor.h:
* add parameter
* is_meeting to
distinguish between events and  meetings.
* gui/dialogs/meeting-page.c:
* (sensitize_widgets):
use explicit GError variable so that BUSY_ERROR
conditions do not lead us to think the calendar is readonly.
* gui/e-meeting-store.c:
* (refresh_queue_remove),
* (ems_init),
(e_meeting_store_remove_attendee), (freebusy_async),
(refresh_busy_periods), (refresh_queue_add): Make free-busy calls
to backends async. Fixed the problem of spurious attendees getting
added to the refresh_data.
