* generator/Parameters.cs : GError handling overhaul
	* generator/SymbolTable.cs : map GError to IntPtr
	* glib/GException.cs : Refactor to use glue.
	* glue/Makefile.am : add the error.c file.
	* glue/error.c : glue for error message string access
	* gtk/makefile.win32 : ref the gdk-imaging-sharp assembly
