    allow class_addcreator to register an additional creator with the namespace prefix if one was used · 7cfac026

    This will allow legacy externals like iemmatrix and zexy to properly load
    aliases the first time when the user instantiates an object with
    [namespace_prefix/alias_name]
    
    This becomes relevant when there are kludge classes that essentially just
    "#include" the original C file of a class and add an alias_setup function
    which just calls the original setup routine. (For example, see iemmatrix.)
    However, such an approach still calls class_new with the original class name.
    Thus "namespace_prefix/classname" gets added to the pd_objectcreator
    methodspace, but "namespace_prefix/alias_name"-- which is what we want--
    does not. This results in a series of 1000 recursive calls into
    pd_objectmaker's new_anything method. (I.e., sys_load_lib finds the
    "namespace_prefix/classname" is already loaded, new_anything_sends a
    typedmess to pd_objectmaker's new_anything method, which calls
    sys_load_lib, etc.)
    
    To prevent this, we just make sure to add "namespace_prefix/alias" by
    adding the relevant lines to class_addcreator. This should really be
    happening anyway-- since internal classes don't have a class_loadsym
    they aren't affected, and externals with aliases won't work with
    namespace prefix without this.
