do nothing if screen is being unmanaged, we don't want to blow away state,

2002-06-22  Havoc Pennington  <hp@pobox.com>

	* src/workspace.c (set_number_of_spaces_hint): do nothing if
	screen is being unmanaged, we don't want to blow away state,
	we want to remember it for the next window manager.

2002-06-22  Havoc Pennington  <hp@pobox.com>

	* src/workspace.c (meta_screen_ensure_workspace_popup): rename
	from meta_workspace_ensure_tab_popup, and use workspace->name
	instead of a hardcoded name
