Fix a load of evil embeddable-grid bugs, fix oaf activation.

2000-05-11  Michael Meeks  <michael@helixcode.com>

	* src/embeddable-grid.c (grid_view_activate): grab widget focus.

	* src/workbook-format-toolbar.c (workbook_feedback_set): make it
	cope with no format toolbar.

	* src/workbook.c (workbook_init): g_new0 for safety and to blank
	edit_line.

	* src/embeddable-grid.c (grid_view_new): set a sensible default
	size so we actually see something. (grid_view_activate): Fix with
	state boolean. (set_header_visibility): implement.
	(embeddable_grid_set_header_visibility): update.
	(grid_view_destroy): kill. (grid_view_new): kill evil private list
	of views.

	* gnumeric.oafinfo: another fix, evil bug from oaf conversion script.
