Solve

Add dilated convolution explanation to convolution arithmetic tutorial

added a blank sandbox/solve.py that just imports solve from slinalg and warns the user that sandbox.solve will soon be deprecated

added documentation for solve. I had to add it to doc/.../slinalg.txt as well otherwise the method signature looked ugly in sphinx

fixing subtensor.take

Small deprecation fix

Update TRAVIS config: tests splitted

Fix issue in local_subtensor_incsubtensor

This fixes an intermittent failure with non-default seed

Adding __props__ to all the Ops that has __init__

Grammar fix

theano/tensor tests splitted aroung theano/tensor/nnet

Fix the optim to replace the gradient of log softmax (true_div problem)

noticed that max_and_argmax fails, test + fix

Port opt from the old backend.

AWS Marketplace AMI install doc section

Correction added based on travis validator at http://lint.travis-ci.org/ .

Added the installation of nose-exclude plugin for nosetests.
This plugin should allow us to exclude folders with `nosetests --exclude-dir=path/to/directory`
Tests rewritten to use nose-exclude and to fix some nosetests syntax about file exclusion.

This is my proposal for GpuMaxAndArgmax (issue #1399).

theano/tensor tests are splitted into:
- all theano/tensor tests excluding test_basic
- just test_basic

`mode=FAST_COMPILE` tests are splitted into:
- all tests excluding theano/tensor tests
- just theano/tensor tests
