.methods doesn't return the full set of results. #34

When we allowed object-methods to be defined they were originally written 100% in golang.

That meant that the golang-implemented methods call could work, outputting the names of all known methods. However now there are methods implemented in monkey.

We should use reflection/introspection to get all methods that work on a given-type, or we should remove the facility entirely. Having wrong results is the worst possible compromise!
