	* src/cell.c (cell_relocate): When relocating a cell with a
	formula, always mark it as changed.  We were doing that before
	only for the case where the location had changed, but we use
	cell_relocate in other cases as well.

	* src/fn-string.c (gnumeric_lower, gnumeric_upper): These
	functions were wrong.  They were never incrementing the pointer
	and they were releasing the wrong pointer.

	* src/clipboard.c (paste_cell): When pasting a cell, mark the
	contents as modified.

	* src/file.c (file_saver_is_default_format): Make sure the saver
	is always set.

	* src/file.c (fill_save_menu): Creates an option menu with the
	file format to save on.
	(workbook_save_as): Use the saver selected by the user.
	(saver_activate): Keep track of the current file save format, set
	as default.
	gnumeric_file_savers, gnumeric_file_openers: made static.

Now we have support for registering/unregistering file opening
and saving formats.

Miguel.

	* plugins/excel/boot.c: New file, this holds the probing and load
	wrapper code for Gnumeric to use as well as the initial format
	registering code.

	* src/xml-io.c (xml_probe): New routine, used to probe if a file
	is a Gnumeric-xml file.

	* src/file.c (file_format_register_open,
	file_format_unregister_open, file_format_register_save,
	file_format_unregister_save): New routines used to register and
	unregister file formats in Gnumeric.

	* src/main.c (main): Boot xml and excel formats, since they now
	need to register themselves with the file.c code

	* src/cell.c (cell_modified): Cells from the clipboard do not have
	a Sheet parameter attached.

	* src/sheet.c (sheet_cell_add): Check the computed style:  if the
	computed style includes a format, then turn on the cell flag for
	format is set to avoid the auto guess of cell content.
	(sheet_style_compute): Now can return the flags of the style that
	were not part of the default style.

	* src/file.c (dialog_query_load_file, workbook_save_as): Put the
	window close to the mouse.

	* src/workbook.c (sheet_check_dirty, workbook_close): Do not
	cancel without warning the user if the workbook has changed.
	(workbook_new, workbook_can_close, workbook_window_destroy,
	quit_cmd, close_cmd): Reorganized the code to suit the new code to
	prevent inadvertent quits.
