- nsf.c: * added NsfClassListNoDup() to allow just single inserts * added NsfClassListPrint() for debugging * info heritage returns no duplicates * added prototype for NsfNoCurrentObjectError() * report "no current object" when no object is passed to a method. * code cleanup - extended regression test
- removed c-implementation of method vwait, it was replaced by "vwait :varName". We had to allow flag TCL_GLOBAL_ONLY in InterpColonVarResolver(), since Tcl vwait implementation calls it with that flag. - added a scripted implementation for vwait in xotcl2
