org.jboss.forge.parser.java.Method needs getGenericReturnType (or equivalent)

Currently, if I have a method...

public List<Foo> getList();

...then org.jboss.forge.parser.java.Method.getReturnType() returns...

java.util.List

There doesn't appear to be a way to get hold of the generic type <Foo>?

java.lang.Method has a special 'getGenericReturnType' method which returns a ParameterizedType which you can then call 'getActualTypeArguments' on. I don't necessarily like that API, but we need some equivalent to it.
