serializer: - added handling of "-debug" and "-deprecated" in serializer - allow export of nsfprocs via "exportMethods declaration" in order to keep otherwise excluded cmds in the result. this allows us to keep nsf::debug::* or nsf::deprecated definitions in the blueprint in OpenACS. - hardened serializer (use e.g. "::namespace" instead of "namespace" when there is a potential conflict with a method named "namespace", prefer nsf::directdispatch, etc.) - extended regression test
- new command nsf::method::forward::property in analogy to nsf::method::property for reading+writing introspection of forwarders (important for serializer, when different target objects are specified, to map the per-object forwarder) - extended regression test - bumped version number of serializer to 2.1
