Conv2d and Pooling2d shape config definition

[syt123450]

Change Conv2d and Pooling2d shape config definition. Conv2d and Pooling2d have shape constructor, however, the shape definition in this constructor have different meaning with the upcoming shape feature ( #152 ).

Change From:

TSP.layers.Conv2d( { filters : Int , shape : [ Int, Int ] } );

Change To:

TSP.layers.Conv2d( { shape : [ Int, Int, Int ] } );

Conv2d and Pooling2d's constructor in next TensorSpace version:

TSP.layers.Conv2d( { shape : [ Int, Int, Int ] } );

TSP.layers.Pooling2d( { shape : [ Int, Int, Int ] } );
