Adding paypaljsbuttons 1.0.2

Adding paypaljsbuttons 1.0.2

The project is located at [https://github.com/paypal/JavaScriptButtons](https://github.com/paypal/JavaScriptButtons)

It's a library used for dynamically creating PayPal checkout buttons.  There are actually two flavors of the script (basic support for buttons, and an add-on for using an interactive cart) but they are all under one npm module.  
How would I go about splitting that up on here?  Create two directories in /ajax/libs?

Thanks!
