Initialize collection field to NULL. Set the collection on the model as

2001-01-22  Christopher James Lahey  <clahey@helixcode.com>

	* gal-define-views-dialog.c, gal-define-views-dialog.h
	(gal_define_views_dialog_init): Initialize collection field to
	NULL.  Set the collection on the model as soon as we create it.
	(gal_define_views_dialog_new): Add a GalViewCollection argument to
	this function.  This just makes this dialog a bit easier to use
	through the API.
	(gal_define_views_dialog_set_arg): When we set the collection, set
	it on the dialog->model.

	* gal-define-views-model.c, gal-define-views-model.h: Rewrote this
	object to use a GalViewCollection to store the information instead
	of an array of GalViews.

	* gal-view-collection.c, gal-view-collection.h: Added
	gal_view_collection_get_count, gal_view_collection_get_view,
	gal_view_collection_append, gal_view_collection_delete_view, and
	gal_view_collection_copy_view.
	(view_changed, load_single_file): Connect to the "changed" signal
	on the views.
	(load_single_dir): Survive loading if there's no xml file.

	* gal-view-etable.c: Implemented get_type_code method.

	* gal-view-factory-etable.c: Implemented get_type_code method.

	* gal-view.c, gal-view.h: Added gal_view_get_type_code and
	"changed" signal.
