Disable “…application downloaded from the Internet.” warning in OS X

I found this online while trying to stop the annoying “Google Chrome is an application downloaded from the Internet.” on an OS X machine I was setting up. Posting here so I can find it quickly again in the future. Obviously put in whatever app you need to do this on in place of the “Google Chrome.app”

Run the following from Terminal:
