More EJI enhancements

[ProjectMoon]

An @EJINamespace annotation on a class without anything else should make a "native script" where all static methods are converted to functions. Then, create a method that scans a class for the EJI namespace annotation and adds it to the interpreter. This will replace the current hardcoded init of the native libraries. It will then be triggered on import, by a paths mechanism. This is the first step to having a true standard library.
