Mismatch to Caffe implementation about c3d-keras HOT 3 CLOSED

I made some progress regarding this.
The padding here is incorrect:
https://github.com/axon-research/c3d-keras/blob/master/c3d_model.py#L49

The original has no padding:
https://github.com/facebook/C3D/blob/master/C3D-v1.0/src/caffe/layers/pool3d_layer.cpp#L46
or, rather it has right only padding, through this:
https://github.com/facebook/C3D/blob/master/C3D-v1.0/src/caffe/layers/pool3d_layer.cpp#L92

by changing above line to
model.add(ZeroPadding3D(padding=((0, 0), (0, 1), (0, 1)), name='zeropad5'))
I now get probablities that are closer to the reference implementation:

         wiffle ball: 28.18%
      knife throwing: 13.11%
             croquet: 10.82%
           disc golf: 7.88%
            rounders: 4.97%
            kickball: 4.46%
               bocce: 3.11%
           boomerang: 2.02%
           dodgeball: 1.78%
      pitch and putt: 1.40%

Also, I used the mean from here, which helped getting more accurate results:

@gyglim thanks for your effort. i was puzzled myself. right-padding instead of symmetric padding did make it close to reference results.

@gyglim : made this change. thanks for your contribution!
