Fully finished with latest bug fixes and added images preprocessing

Now we can preprocess our images before we use them to train our neural network.
We can use the following filters:

• Gray Scale
• Auto Crop
• Equalize histogram

Also added skipping phases of training and (un)selecting all categories.

Newest features allow also to save whole trained deep belief network with train parameters altogether!

General fixes + added logging
