It's here!

Big thanks to @ilyakatz for the making of this script and @psgs who assisted us. You're awesome guys :heart: 

So this ruby script adds new sites and providers to the yaml files. Hopefully this will help people not make yaml errors.
The script will also put all the sites/providers in an alphabetic order which is a solution to #873.

We feel like the script is done so I'm now making this merge request of the script branch.

If you can't tell already, I'm super excited about this :smile:
