Rachel Hestilow f1a77c0e62 2003-05-19 Rachel Hestilow <rachel@nullenvoid.com>
* glib/ManagedValue.cs, TypeConverter.cs: Added.
	* glib/Value.cs: Make Value inherit from IDisposable, and
	move dtor to Dispose. Add generic object constructor
	with support for ManagedValue. Add a new Val property
	which will call the appropriate explicit cast.

	* glue/value.c: Add new glue function
	gtksharp_value_get_value_type.

	* gtk/TreeViewColumn.custom: Added.
	* gtk/ListStore.custom, TreeStore.custom: Add a number
	of SetValue overloads. Add convenience functtion
	AppendValues. Add new ctor that takes System.Type instead
	of GLib.TypeFundamentals. Add a GetValue convenience wrapper.
	* gtk/TreeView.custom: Add AppendColumn convenience
	functions.

	* sample/ManagedTreeViewDemo.cs: Added.
	* sample/Makefile.in: Update.
	* sample/TreeViewDemo.cs: Update to use new convenience
	APIs.
