 - New GPU back-end:

   - Added useful stats for GPU in profile mode
   - Added documentation for GPU float16 ops


Interface changes:
 - Changed ``grad()`` method to ``L_op`` in ops that need the outputs to compute gradient
 - Merged duplicated diagonal functions into two ops: ``ExtractDiag`` (extract a diagonal to a vector),
   and ``AllocDiag`` (set a vector as a diagonal of an empty array)

Convolution updates:
 - Extended Theano flag ``dnn.enabled`` with new option ``no_check`` to help speed up cuDNN importation


GPU:
 - ...

New features:
 - Added scalar and elemwise ops for modified Bessel function of order 0 and 1 from ``scipy.special``


Others:
 - ...
