	* gui/migration.c (migrate_ical_folder_to_source): migrate to a
	specific source
	(migrate_ical_folder): create a new source based on the new source
	name/uid
	(create_calendar_contact_source): use the #define for the base uri
	(create_calendar_sources): try and find the right sources if they
	already exist
	(create_task_sources): ditto
	(migrate_calendars): make sure the personal source is the system
	source
	(migrate_tasks): ditto
