Rails demo application with Token and Charge creation

Not sure I'd do it this way. Maybe better to implement this in term of what people usually are looking for. Something like an Order that you have to pay.

order = @current_customer.new_order(amount_subunits: 100000, currency: "thb")

@card = if params[:save_card].present?
  @current_customer.attach_card(params[:omise_token])
elsif params[:card_id].present?
  @current_customer.find_card(params[:card_id])
end

if @card
  order.pay_with_customer_card(@card.id)
else
  order.pay_with_token(params[:omise_token])
end

if order.paid?
  redirect_to thanks_url(order)
else
  redirect_to checkout_url
end

OK great :smile:

Will you do it in this PR or you want this merged first and do a new one later?

[fred]

I'll do in this PR since I might change the database structure.
