nx.tcl: - replaced functionality of "/obj/ configure" by "/obj/ info configure" to re-enable semantics of the plain configure method, even when called without arguments. "/obj/ info configure" is actually a convenience method to allow to write o1 info configure instead of o1 info lookup configure syntax
nsf.c - fixed potential inifinite loop in pattern matching for precedence lists - cget: make error message closer to tcl conventions - extended regression test
