Use singular and plural table name to generate properly namespaced controllers

The controller that was generated when creating a namespaced resource was: 

```ruby
class Client::OrdersController < ApplicationController
  before_action :set_order, only: [:show, :edit, :update, :destroy]

  def index
    @client_orders = Client::Order.all
    respond_with(@client_orders)
  end

  def show
    respond_with(@order)
  end

  def new
    @order = Client::Order.new
    respond_with(@order)
  end

  def edit
  end

  def create
    @order = Client::Order.new(order_params)
    @client_order.save
    respond_with(@order)
  end

  def update
    @client_order.update(order_params)
    respond_with(@order)
  end

  def destroy
    @client_order.destroy
    respond_with(@order)
  end

  private
    def set_order
      @order = Client::Order.find(params[:id])
    end

    def order_params
      params.require(:order).permit(:title)
    end
end
```
This change will create a proper controller such as this one:

```ruby
class Client::OrdersController < ApplicationController
  before_action :set_client_order, only: [:show, :edit, :update, :destroy]

  def index
    @client_orders = Client::Order.all
    respond_with(@client_orders)
  end

  def show
    respond_with(@client_order)
  end

  def new
    @client_order = Client::Order.new
    respond_with(@client_order)
  end

  def edit
  end

  def create
    @client_order = Client::Order.new(order_params)
    @client_order.save
    respond_with(@client_order)
  end

  def update
    @client_order.update(order_params)
    respond_with(@client_order)
  end

  def destroy
    @client_order.destroy
    respond_with(@client_order)
  end

  private
    def set_client_order
      @client_order = Client::Order.find(params[:id])
    end

    def client_order_params
      params.require(:client_order).permit(:title)
    end
end
```
