Add drush make files

Hi Kristen,

I am reading your book and trying out the "Drupal 7 Multilingual Sites Book Demo Installation Profile", but it seems to be crashing on my end... (the test site has user kristen, I hope you do not mind)

Do you have any thoughts on this!? (I am using the 7.x-1.0-alpha8)

Starting Drupal installation. This takes a few seconds ...                                                                                                                                                                    [ok]
