[Equal credit to Ettore Perazzoli <ettore@ximian.com> for fixing
	all the bugs in the initial patch]
	* */*.custom : fix incorrect usage of new Object (IntPtr) where
	Glib.Object.GetObject should've been used.  add ref_owned param
	to GetObject calls.
	* generator/CallbackGen.cs : setup ref_owned in bodies
	* generator/ClassBase.cs : add ref_owned to GetObject FromNative call
	* generator/Method.cs : setup ref_owned in bodies
	* generator/Property.cs : setup ref_owned in bodies
	* generator/SignalHandler.cs : pass ref_owned to GetObject
	* generator/StructBase.cs : setup ref_owned in bodies
	* glib/Object.cs : kill Ref/Unref methods.  Don't want it to be
	easy for users to screw with ref counts, or make it look like they
	should need to.
	(GetObject): add ref_owned param and ref/unref to remain at 1
	* glib/Value.cs : pass ref_owned to GetObject
