What changed

Fix #531: Support static member functions via ClassName.func() syntax
Add a new overload of utility::add_class that accepts a fifth parameter
for static functions. Static functions are registered as attributes of a
Dynamic_Object namespace with the class name, enabling ClassName.func()
call syntax. To allow constructors to coexist with the namespace global,
Fun_Call_AST_Node now falls back to dispatch-by-name when the evaluated
identifier is not directly callable.
