ToolShell: Add ellipsize, text-orientation, text-alignment and size-group.

* gtk/gtktoolshell.c: Added vfuncs to get/set ellipsize, text-orientation,
	text-alignment and size-group plus getter/setters to invoke these vfuncs.
	* gtk/gtktoolitem.[h|c]: Added getters and setters to get/set these from the
	parent GtkToolShell. This is in the style of the existing "properties".
	* gtk/gtktoolbutton.c: Updated to use the extra properties.

	* docs/reference/gtk/gtk-sections.txt
	* gtk/gtk.symbols: Updated to mention the new functions.

	These new "properties" are used by GtkToolPalette.
