Java std::vector improvements for types that do not have a default constructor.

The std::vector wrappers have been changed to work by default for elements that are
not default insertable, i.e. have no default constructor. This has been achieved by
not wrapping:

  vector(size_type n);

Previously the above had to be ignored via %ignore.

If the above constructor is still required it can be added back in again via %extend:

  %extend std::vector {
    vector(size_type count) { return new std::vector< T >(count); }
  }

Alternatively, the following wrapped constructor could be used as it provides near-enough
equivalent functionality:

  vector(jint count, const value_type& value);

The equivalent change to std::list has also been made (std::list
wrappers were not in the previous release [3.0.12] though).
