Some regularizers do not work

[amanoel]

Hello,

I just noticed something weird in the code and thought it would be helpful to share it with you: the fact that the copy function makes a copy of the regularizer with no arguments, i.e.,

function copy(r::Regularizer)
  newr = typeof(r)()
  for field in @compat fieldnames(r)
    setfield!(newr, field, copy(getfield(r, field)))
  end
  newr
end

make it impossible to use regularizers that do require an argument, for instance fixed_latent_features and fixed_last_latent_features.
I guess one could solve this by also copying the arguments?

There are a few ways to fix this. One is to define default parameters for every regularizer, so typeof(r)() works. Another is to more cleverly copy the fields of the regularizer. I'd welcome a PR.
