Make `content_tag_for` and `div_for` accepts the array of records

So instead of having to do this:

   @items.each do |item|
     content_tag_for(:li, item) do
        Title: <%= item.title %>
     end
   end

You can now do this:

   content_tag_for(:li, @items) do |item|
     Title: <%= item.title %>
   end
