Added data_query_order_by function

Nathan,

I added a data_query_order_by function to the data.rb file. The modification worked well on my local install of your gem. It would be great if you could include this.

ASIDE: I wonder if you had any insight into a problem I was having. After forking from your repo and modifying the data.rb file, I tried to have my Gemfile use the my modified version by using:

gem 'infusionsoft', :git => 'git://github.com/inportland99/infusionsoft.git'

unfortunately, even though bundle install seemed to pull the files from my repo, the gem did not work at all. Do you know why?

BTW - Thanks for putting together the infusionsoft gem… it's been a godsend.
