Composer: Show cancellable operations and errors inline.
'Send' and 'Save Draft' are now asynchronous and run outside of Evolution's MailMsg infrastructure. Add an EActivityBar to the composer window so these asynchronous operations can be tracked and cancelled even in the absense of a main window. Also add an EAlertBar to the composer window so error messages can be shown directly in the window. Instead of calling e_alert_dialog_run_for_args(), call e_alert_submit() and pass the EMsgComposer as the widget argument. The EMsgComposer will decide whether to show an EAlertDialog or use the EAlertBar, depending on the GtkMessageType of the alert.
