#2296401: Recurly.js v3
Updated to use Recurly.js v3. The library is now dynamically loaded and no longer needs to be downloaded and placed in your codebase. When upgrading from 7.x-1.x to 7.x-2.x, you can delete the recurlyjs library.

• The recurlyjs module no longer uses custom form elements.
• Recurlyjs is now configured with a Public Key, not the Transparent Post key.
• The billing forms are now created by Drupal, not Recurly, but processed by Recurly, as detailed above.
• The dev release does not yet have PayPal or bank account support.
• Form elements have been changed and the existing css no longer applies, this needs a refactor.
