Put a wrapper in place around dialog creation.  This will eventually handle the
setting of the parent and closing the parent application while a dialog is up.

2000-01-21  Jody Goldberg <jgoldberg@home.com>

	* src/dialogs/dialog-printer-setup.c (do_hf_config) : Take a Workbook.

	* src/gnumeric-util.c (gnumeric_dialog_run) : New function.
	  It is a wrapper for now.  After the release of .48 we will
	  move the parent setting here.  And handle the case where a
	  user closes the app window while a dialog is displayed.

	* src/file.c (workbook_import) : Use gnumeric_dialog_run.

	* src/dialogs/dialog-{dialog-zoom.c (dialog_zoom_impl)
		    summary.c (dialog_summary_update)
		    solver.c (dialog_solver)
		    solver.c (constr_add_click)
		    solver.c (dialog_solver_options)
		    simple-input.c (dialog_get_number, dialog_get_sheet_name)
		    printer.c (gnumeric_printer_dialog_run)
		    paste-special.c (dialog_paste_special)
		    insert-cells.c (dialog_insert_cells_impl)
		    goto-cell.c (dialog_goto_cell)
		    goal-seek.c (dialog_found_solution, dialog_goal_seek)
		    function-wizard.c (dialog_function_wizard)
		    delete-cells.c (dialog_delete_cells_impl)
		    cell-sort.c (dialog_cell_sort)
		    cell-format.c (fmt_dialog_impl)
		    cell-comment.c (dialog_cell_comment)
		    autosave.c (dialog_autosave_callback, dialog_autosave)
		    autocorrect.c (exceptions_callback)
		    (dialog_autocorrect)} : Ditto.

	* src/dialogs/dialog-analysis-tools.c
	(dialog_{correlation_tool, covariance_tool, sampling_tool,
	 descriptive_stat_tool, ztest_tool, ttest_paired_tool, ttest_eq_tool,
	 ttest_neq_tool, ftest_tool, random_tool, regression_tool,
	 average_tool, ranking_tool, anova_single_factor_tool,
	 anova_two_factor_without_r_tool, data_analysis}) : Ditto.

	* src/workbook.c (workbook_can_close) : Ditto.
	* src/item-cursor.c (item_cursor_target_region_ok) : Ditto.

	* src/sheet.c (sheet_move_range) : Avoid leaking when we paste.
	  This information will be used when undo for pasteing a cut
	  is ready.

	* README : update requirements.

	* plugins/Makefile.am : Do not compile the python plugin by
	  default.  This will avoid complaints regarding problems with
	  no dynamic python library until we have a solution.

	* src/functions/fn-stat.c : (gnumeric_kurt, gnumeric_kurtp) : return DIV/0
	  on error.
