Migrate the ETree expanded state files as well as the GalView files.

2004-01-21  Jeffrey Stedfast  <fejj@ximian.com>

	* em-migrate.c (em_migrate_1_4): Migrate the ETree expanded state
	files as well as the GalView files.

	* message-list.c: s/hide_save_state/save_hide_state/g and
	s/hide_load_state/load_hide_state/g to be more consistant with the
	other state saving function names.
