  BUG: Fix recarray getattr and getindex return types

This commit makes changes to `__getitem__` and `__getattr__` of recarrays:

 1. recarrays no longer convert string ndarrays to chararrays, and
    instead simply return ndarrays of string type.
 2. attribute access and index access of fields now behaves identically
 3. dtype.type is now inherited when fields of structured type are accessed

Demonstration:

    >>> rec = np.rec.array([('abc ', (1,1), 1), ('abc', (2,3), 1)],
    ...       dtype=[('foo', 'S4'), ('bar', [('A', int), ('B', int)]), ('baz', int)])

Old Behavior:

    >>> type(rec.foo), type(rec['foo'])
    (numpy.core.defchararray.chararray, numpy.recarray)
    >>> type(rec.bar), type(rec['bar']), rec.bar.dtype.type
    (numpy.recarray, numpy.recarray, numpy.void)
    >>> type(rec.baz), type(rec['baz'])
    (numpy.ndarray, numpy.ndarray)

New behavior:

    >>> type(rec.foo), type(rec['foo'])
    (numpy.ndarray, numpy.ndarray)
    >>> type(rec.bar), type(rec['bar']), rec.bar.dtype.type
    (numpy.recarray, numpy.recarray, numpy.record)
    >>> type(rec.baz), type(rec['baz'])
    (numpy.ndarray, numpy.ndarray)
