add some simple support for base object methods

add "module_version", "module_api_version" and "module_description" as
base object methods. All classes based on func_module should get this.

modules should set a self.version, self.api_version, self.description
with approriate values. class or instance variables both work. If
values aren't set, defaults are provided.

alternativelt, the modules can implement and export "module_version",
"module_api_version", and "module_description" themself if they
like
