Password field type

[Jaza]

With this change, if you define:

defmodule MyApp.UserAdmin do
  def form_fields(_) do
    [
      password: %{type: :password}
    ]
  end
end

Then it will display an input of type "password" in the kaffy create/edit form.

Ideally, kaffy could also infer that it should be a password input, based on the schema field having redact: true . But, as far as I can tell, from some quick debugging, that isn't coming through to build_html_input/6 . Anyway, with this change, you can at least force a given field to have a password input.
