- nsf.c: made potentially unknown clientData more safe (error message, when something is passed via clientData to a method expecting an object/class as clientData). - renamed NsfNoDispatchObjectError() to NsfDispatchClientDataError(), extended interface - Makefile.in: fixed name methods.test
* Hopefully the last big naming change: Instead of writing "C class-object method foo {} {...}" one can write now "C class method foo {} {...}" to define a class method named "foo" for class "C". This naming change became possible by defining XOTcl's "class" (and "superclass") as object parameter only. To change a class of an object o, one has to use "o configure -class NEWCLASS". The term "object-class" looks alien to language beginners, the term "class" is much more straightforward. Changing classes or superclasses is seldomly used by typicall application programs. For already existing nx scripts, changing "object-class" into class should be straightforward.
