-added flag -checkalways to nsf::proc and nsf::asm::proc (for the latter just a placeholder for now). If the flag is used, it will cause argument testing independently from the "configure checkarguments" setting. To force argument checking always is useful e.g. for checking external values (e.g. in a web server)
nsf.c - removed obsolete function AssertionAppendPrePost() - removed obsolete function NsfNSCopyCmdsCmd() and ::nsf::nscopycmd (handled now more general on scripting level in the "copy" method) nx.tcl: - "copy" method: fixed copying of class-level per-object methods - extended regression tests
