Almost finished with the Paypal Express Checkout API library :)
So far about 7 hours of work just to understand the API, rewrite a (probably) working CI-library (with *bad* coding standards) to match our system, librarys and "my way of doin' it"...
Added PayPal config args to dbconfig + changed comments on the previous ones to better understand what they are used for.
Added CSRF-exclude patch for CI from git-repo.
Massive commit with a (pretty much) completed PayPal library. :)
