This make this test work. It was crashing during the compilation:

THEANO_FLAGS=device=gpu,floatX=float32 theano-nose theano/tensor/tests/test_basic.py:PsiTester

Py3k Fixes Bugfixes

This locals() wasn't inside a list comprehension and was also replaced
incorrectly.

StringIO was moved in python 3.

Rebase2

Instead of non-portable symlink from NEWS.txt to doc/NEWS.txt

It is intended to be ran by users so there is no reason to not have it executable

Py3k Fixes Part 2

Fixes for python 3 compatibility.

This is needed as a previous commit changed some python int to numpy integer.

This will also make the optimization happen more frequently then before.

This allow theano.tests() to run more tests!

This change the behavior a little. Now int are casted into
numpy.int64. This is needed as in Python3 long have replaced int and
there are no more long! So the int case will be used in Python 3.

Forcing the type isn't a problem as we support only this type for
shape everywhere in Theano.
