[mlpack] L2 Regularization for NN

[Marcus Edel]

Hello Eugene,

Currently, it's not possible to apply penalties on layer parameters or layer
activity during the optimization process. However, it should be straightforward
to implement a layer that can apply penalties. Another option would be to
implement it as a decay policy so that it can be used inside the optimizer.

Thanks,
Marcus
