Moved et2 core interfaces to own file; implemented Class.free which cares about calling 'destroy', removing all references the object may hold and rendering the object unusable after 'free' has been called; added 'getMem_freeMem_trace' which helps hunting down memory leaks with objects derriving from Class; added first implementation of the nextmatch widget - currently does nothing else but rendering the header and clicking on the nextmatch_sortheader labels
