slowly fixing Paypal

[scottwarren]

Todo

• [ ] Fix Paypal
  • [ ] Get a payment back from Paypal, even if it's a test one
  • [ ] Get real details and put in the Settings.yml
  • [ ] Use fake/real details depending on environment
  • [ ] Have success return and fail/cancel URLs
  • [ ] Fix bug where Paypal is throwing a security error (I think it has to do with not using the Paypal Sandbox environment (I have tried to use: Paypal.sandbox! if Rails.env.development? but no luck thus far))

I am going to split out the Amazon from this PR because this is going to be a lot of changes as it is

@benmort do you want to have a look at this? I am having a constant error when trying to checkout:

PayPal API Error: 'Security error'

This basically occurs only when the API keys are wrong, but my stuff is right. Can you take a look with some credentials of yours?
