also change this behavior with config.int_division).

* Casting behavior is closer to numpy by default, and can be controlled
through config.cast_policy.
* Smarter C module cache, avoiding erroneous usage of the wrong C
implementation when some options change, and avoiding recompiling the
same module multiple times in some situations.
* The "theano-cache clear" command now clears the cache more thoroughly.
* More extensive linear algebra ops (CPU only) that wrap scipy.linalg

* CUDA devices 4 - 16 should now be available if present.
