add two output maps in diagonal BiLSTM

[powder21]

output_state_bw_with_last_zeros = tf.concat(1, [output_state_bw_except_last, dummy_zeros])

should be

output_state_bw_with_last_zeros = tf.concat(1, [dummy_zeros, output_state_bw_except_last])

yes, I think you are right! In https://github.com/igul222/pixel_rnn theano code just do like that.
