nsf.c: - extended nsf::method::delete to handle ensemble names nx.tcl: - added tk/incr-tcl style cget methods on class/object levels. - improve copy handling with other child-types of the slot container working - make sure to ignore non-slot-type objects in slot introspection - worked on regression test until "methods.test". others are missing, but maybe reconsideration
- generic/nsf.c, ObjectDispatch(): Re-arranged the handling of fully-qualified method dispatches with the selectors resolving to existing objects and, in particular, nested (namespace-qualified) objects. Prior to that, dispatches such as "::C ::parent::child" were not covered appropriately: ::parent was reported as valid regObj and so the dispatcher continued to dispatch to the cmd "::parent::child" in the self-context ::parent::child ... with unwanted side-effects (e.g., XOTcl's unknown handling was bypassed). - tests/methods.test: Added basic tests on the (current) handling for such ::* dispatches and a specific test set on the intended XOTcl behaviour.
