Java std::vector std::list enhancements

- Add missing vector copy constructor
- Add constructor to initialize the containers. Note that Java's
  equivalent constructor for ArrayList just sets the capacity, whereas
  the wrappers behave like the C++ constructor and set the size. I've
  done this mainly because there has been a vector(size_type) constructor
  in the Java wrappers for many years, so best to keep this unchanged.
