Licenses content

Hey, I have added licenses content because it looks useful to me, but Im not sure if you want it also so feel free to ignore this :)
Yeah I agree that its fragile :/ But that link contains all the licenses with git metadata so it might be hard to parse it for specific license. 

What about just cloning that git repository? http://git.spdx.org/license-list.git (but Im not sure if its good idea to call it form node and also it will create another git repository inside this one)
