Keras 2.0 support

[kmader]

Trying to use a model exported by Keras 2 the first layer has an issue since the Convolution2D has been renamed Conv2D (layer.class_name) in the newer API

when processing block1_conv1 0 Conv2D

keras-model-editor.js:19860 Uncaught TypeError: Cannot read property 'color' of undefined

you may modify https://github.com/neurals-ro/keras-model-editor/blob/master/lib/keras_conf_v1.js according to the changes in Keras or even have a new file with the configurations with the name keras_conf_v2.js and use that one in: https://github.com/neurals-ro/keras-model-editor/blob/master/index.js#L39

Then, we would appreciate a PR on "v2" :)
