- made methods (for now just scripted methods) by default protected. - provide methode __default_method_protection to obtain the default method protection when neither protected or public is used. - per default methods are now protected - provide ::nx::configure defaultMethodProtection true|false as conveniant interface - update regression test and serializer to handle default protection
- new nsf::next cmd. receives 0 or 1 argument, which might be a list of arguments. This avoids ambiguity of ::xotcl::next with "--noArgs". - renamed namespace_copycmds and namespace_copyvars to nscopycmds and nscopyvars (we don't use "_" in nsf::*-names as delimiters elsewhere) - renamed __qualify to qualify (it is a non-exported cmd)
