Inconsistent conversion of PyObject to String in StdoutWrapper

Given some object o, executing

  print o

causes Jython to build a string representation of o to be displayed on the console.

The conversion is done differently depending on whether stdout/stderr are accessed through a PyFile or a PyFileWriter.

Jython uses PyFile by default, and results in an object's __str__ method being called.

PyFileWriter causes an object's __repr__ method to be called instead, which is inconsistent with CPython.
