- moved "-per-object" consequently immediately after obj in the following commands : ::xotcl::alias, ::xotcl::methodproperty, ::xotcl::setter to achiev conformance with ::xotcl::forward and ::xotcl::method
- added ::xotcl::forward as cmd instead of method now, all method-defining-methods (alias, method, forward, setter) are defined as cmds (this should make life of serializer easier)
