Production environment problem

[osoner]

First of all thanks a lot for this great module. I've found below issues about production usage. I'm not sending a pull req in case you might wanna change the implementation.

• The environment property needs to be given as the second parameter to the constructor in order work

  var Paypal = require('paypal-recurring'),
    paypal = new Paypal({
      username:  "info@example.com",
      password:  "****",
      signature: "****"
    }, "production");

• Line 33 should be changed from cgi?bin to cgi-bin
