Request to add support of multiple nested levels of params

[clamoris]

I have something like this in a project:

  param :validations, Hash  do
    param :global, Array, :desc => "Global validations" do
      param :id, String, :desc => "Id of validation", :required => true
      param :type, %w(aaa bbb ccc), :desc => "Validation type"
    end
    param :per_item, Array, :desc => "Validations for specific item" do
      param :id, String, :desc => "Id of item", :required => true
      param :validations, Array do
        param :id, String, :desc => "Id of validation", :required => true
        param :type, %w(aaa bbb ccc), :desc => "Validation type"
      end
    end
  end

But in documentation, I see only
validations[global]
validations[per_project]
With a description like "Value: Must be an Array of nested elements"

I'd like to be able to see full param tree

Looks good to me, thanks!)
Also, bump version please, if it not a big trouble.
