	* dialog-search.c (dialog_search): Don't install as guru.  Attach
	signal to close dialog if workbook has sheets removed.  Allow more
	than one search open at a time.
	(search_clicked): Install a new model.  That avoids inserting one
	line at a time.

	* dialog-stf-preview.c (stf_preview_free): Unref ->tree_view.
	(stf_preview_new): Ref ->tree_view.
	(stf_preview_set_lines): Switch in a new model for ->tree_view.
	That avoids inserting one line at a time.  This also lifts the
	limit of the column count.
