- disabled fix_filter becaus theano uses "filter" as a method name;
 - fixed another instance of checking the error message;
 - fixed another instance affected by numpy isinstance(x, int) bug.

  * allow numpy array as an argument to hash_from_code.
  * use truediv instead of div under 3.x.
  * **kwds checks that keys are strings in 3.x
  * fixed a typo bug in tensor/opt.py
  * fixed an incorrect numpy version check in test_basic

  * Use PyCapsule instead of PyCObject.

  * Use Python 3 module initialization.

  * Prepend 'm' to code hash to avoid module names that start with a digit.

  * Suppress 2to3's "next" fixer that conflicts with having non-iterator attributes called "next."
     Rely on six.next instead.

   * added python 3 version of hash_from_code.

Update comment after code review.

Fix test and update NEWS.txt

We explicitly use and -inf in the graph, so DebugMode shouldn't complain about this.

Issue #783: python3 compatible - remove unnecessary imports.

A few improvements to function()

This commit is the first step of the plan to make Theano imports compatible with 3.x:

1. Remove unnecessary imports.

2. Convert relative imports to absolute.

3. Fix circular dependency issues by either eliminating "from xyz" imports or moving them inside functions.
