Only try to pack icon if there actually is one.

Sat Jan 24 23:17:27 2004  Soeren Sandmann  <sandmann@daimi.au.dk>

	* gtk/gtktoolbutton.c (gtk_tool_button_construct_contents): Only
	try to pack icon if there actually is one.

	* gtk/gtktoolbar.c (gtk_toolbar_size_allocate): Make sure
	OVERFLOWN items get an allocation even when they are
	unmapped. This ensures they will slide in properly.

	* gtk/gtktoolbar.c (slide_idle_handler): Make sure we return TRUE
	when there are overflown items that need to slide in. Also add
	comments and make formatting more readable.
