Fix easy_install problem with importing theano and revert "RELEASE=True" to False, file should never be checked in with RELEASE=True.

Enable sparse elemwise multiplication by a something that can be converted to a tensor but is not a tensor or a sparse. Test it(and add test for all sparse mul at the same time)

using Variable's comparison operators

Need to swap inheritence order for class ScalarVariable: inherit
_scalar_py_operators first, then Variable

inc_subtensor/set_subtensor.

* changed inheritance order of TensorVariable to include _py_operators before
Variable, so that TensorVariable can use the comparison operators defined in
_py_operators

inc_subtensor/set_subtensor, as the previous implementation is now deprecated.

import the version of theano and nothing else. In some case we could import the version from another project.
