	(map_sax_parse): Parse the given file and build a pilot_id->uid

	* conduits/todo/e-todo.conduit.in: A little renaming

	* conduits/todo/Makefile.am: Fix build slightly

	* pcs/cal.c (build_change_seq): Build a corba sequence out of a
list
	of CalObjChanges
	(Cal_get_objects_in_range): Implement new corba function

	* pcs/cal-backend.c (cal_backend_init): Intiliaze to NULL
	(cal_backend_load): Track the uri so we can write the log file
	to the same place
	(cal_backend_log_name): Figure out the log filename/path based on
	the calendar uri
	(cal_backend_set_node_timet): Set an xml node property value from
	a time_t
	(cal_backend_log_entry): Adds a log entry to list waiting to be
written
	out
	(cal_backend_log_sync): Syncs the log entries to disk
	(cal_backend_log_sax_start_element): SAX callback for reading in
	log entries
	(cal_backend_log_sax_end_element): ditto
	(cal_backend_log_sax_parse): Main SAX parser call to parse the log
	file looking for particular log entries and creating a
CalObjChange
	hash with the last change for each object
	(cal_backend_get_log_entries): Returns a hash of objects of a
given
	type changed since the given time
	(cal_backend_update_object): Add appropriate log entries
	(cal_backend_remove_object): ditto
	(cal_backend_get_changed_uids): Implement new idl interface call
	(cal_backend_foreach_changed): Convert CalObjChange hash into a
list

	* pcs/cal-backend-imc.[hc]: Remove crufty files

	* pcs/cal-backend-file.c (cal_backend_file_get_type_by_uid): New
	function that returns the CalObjType for a uid.

	* cal-client/cal-client.h: Update prototypes.

	* cal-client/cal-client.c (build_change_list): Build a list
	of CalObjChange items from a corba sequence.
	(cal_client_get_changed_uids): New accessor method for the
	similarly named addition to the idl file.

	* cal-util/cal-util.h: Update prototypes and add CalObjChangeType
	enum.

	* cal-util/cal-util.c (cal_obj_change_list_free): New utility
	method to free a list of CalObjChange objects.

	* idl/evolution-calendar.idl: Add get_changed_uids method
	and associated types.
