Gh 1122

Fix tests crash in DebugMode recently introduced.

Now we keep the original error message type and just add more information to it.

Make a tests more robust to different seed

code cleanup

The error is due to rounding difference. The test that fail randomly is theano/sandbox/cuda/tests/test_conv_cuda_ndarray.py:TestConv2DGPU.test_logical_shapes.

Normally, we should set atol depending of the input shape, but the current structure don't allow this, so I use the output shape. So this could happen with other tests if the output shape is smaller.

Remove duplicate code, it is done in the imported test_basic_op

New backend: GpuCrossentropySoftmaxArgmax1HotWithBias, GpuCrossentropySoftmax1HotWithBiasDx

Remove duplicate computation and compilation.

Fix the final stuff.

As a side effect don't always loop over user provided cxx flags always when it contain march.

Make DebugMode raise a better error when an optimization insert an op

Py24

Fix gradient of split when there are disconnected outputs

This should fix gh-1589

Scipy 0.13 (needed for the release)

It used to support ndarray of 2 elements for idx, now it ask for a tuple.

Make Theano use the proper path on Windows with Canopy installed for all users.
Mark ProfileMode as deprecated in the docs and document config.profile.
