Proper GList, GSList support. Read-only for now.

	* glue/list.c: Added.
	* glue/Makefile.am: Add list.c
	* glue/type.c: Add function gtksharp_is_object.

	* glib/ListBase.cs, List.cs: Added.
	* glib/SList.cs: Inherit from ListBase.
	* glib/Object.cs: Add static method "IsObject".

	* generator/Method.cs: Pass on element_type to constructor
	if specified.
	* generator/SymbolTable.cs: Move GList to manual types.

	* sample/GladeViewer.cs: Remove list hacks.

	* sources/Gnome.metadata: Specify element types for
	CanvasPathDef.Split and IconList.GetSelection. Rename
	CanvasPathDef *to methods to properly capitalized *To.
	* sources/Gtk.metadata: Hide Widget.ListAccelClosures until
	GClosure is handled properly.
	* sources/Pango.metadata: Added.

	* sample/test/TestToolbar.cs: Compile with recent delegate changes.
